Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612998, here are decompositions:

7 + 31612991 = 31612998
17 + 31612981 = 31612998
29 + 31612969 = 31612998
37 + 31612961 = 31612998
47 + 31612951 = 31612998
59 + 31612939 = 31612998
107 + 31612891 = 31612998
167 + 31612831 = 31612998

Showing the first eight; more decompositions exist.
