Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625982, here are decompositions:

13 + 31625969 = 31625982
19 + 31625963 = 31625982
29 + 31625953 = 31625982
43 + 31625939 = 31625982
71 + 31625911 = 31625982
139 + 31625843 = 31625982
163 + 31625819 = 31625982
229 + 31625753 = 31625982

Showing the first eight; more decompositions exist.
