liek Given a number sequence, split the number sequence into consecutive digits, and then output how many of these 2-digit sequences are primes.
## Explanation
For example, `7112971` gets splitted into:
```
[71,11,12,29,97,71]
```
You are required to find our how many of these numbers are primes.
## Test cases
|Input|Output|
|:---:|:----:|
|`619737131179`|`11`|
|`7112971`|`5`|
|`7834741`|`3`|
|`127456398`|`0`|
