Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617030, here are decompositions:

7 + 31617023 = 31617030
17 + 31617013 = 31617030
19 + 31617011 = 31617030
31 + 31616999 = 31617030
43 + 31616987 = 31617030
79 + 31616951 = 31617030
97 + 31616933 = 31617030
101 + 31616929 = 31617030

Showing the first eight; more decompositions exist.
