Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617078, here are decompositions:

5 + 31617073 = 31617078
29 + 31617049 = 31617078
67 + 31617011 = 31617078
79 + 31616999 = 31617078
127 + 31616951 = 31617078
149 + 31616929 = 31617078
191 + 31616887 = 31617078
239 + 31616839 = 31617078

Showing the first eight; more decompositions exist.
