Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617084, here are decompositions:

7 + 31617077 = 31617084
11 + 31617073 = 31617084
61 + 31617023 = 31617084
71 + 31617013 = 31617084
73 + 31617011 = 31617084
97 + 31616987 = 31617084
151 + 31616933 = 31617084
167 + 31616917 = 31617084

Showing the first eight; more decompositions exist.
