Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616904, here are decompositions:

13 + 31616891 = 31616904
17 + 31616887 = 31616904
47 + 31616857 = 31616904
131 + 31616773 = 31616904
157 + 31616747 = 31616904
197 + 31616707 = 31616904
211 + 31616693 = 31616904
227 + 31616677 = 31616904

Showing the first eight; more decompositions exist.
