Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601422, here are decompositions:

5 + 31601417 = 31601422
11 + 31601411 = 31601422
29 + 31601393 = 31601422
563 + 31600859 = 31601422
599 + 31600823 = 31601422
701 + 31600721 = 31601422
719 + 31600703 = 31601422
911 + 31600511 = 31601422

Showing the first eight; more decompositions exist.
