Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617086, here are decompositions:

13 + 31617073 = 31617086
37 + 31617049 = 31617086
73 + 31617013 = 31617086
157 + 31616929 = 31617086
199 + 31616887 = 31617086
229 + 31616857 = 31617086
313 + 31616773 = 31617086
337 + 31616749 = 31617086

Showing the first eight; more decompositions exist.
