Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616948, here are decompositions:

19 + 31616929 = 31616948
31 + 31616917 = 31616948
61 + 31616887 = 31616948
109 + 31616839 = 31616948
199 + 31616749 = 31616948
241 + 31616707 = 31616948
271 + 31616677 = 31616948
277 + 31616671 = 31616948

Showing the first eight; more decompositions exist.
