Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616934, here are decompositions:

5 + 31616929 = 31616934
17 + 31616917 = 31616934
31 + 31616903 = 31616934
43 + 31616891 = 31616934
47 + 31616887 = 31616934
227 + 31616707 = 31616934
241 + 31616693 = 31616934
257 + 31616677 = 31616934

Showing the first eight; more decompositions exist.
