Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617110, here are decompositions:

37 + 31617073 = 31617110
61 + 31617049 = 31617110
97 + 31617013 = 31617110
181 + 31616929 = 31617110
193 + 31616917 = 31617110
223 + 31616887 = 31617110
271 + 31616839 = 31617110
337 + 31616773 = 31617110

Showing the first eight; more decompositions exist.
