Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616930, here are decompositions:

13 + 31616917 = 31616930
43 + 31616887 = 31616930
73 + 31616857 = 31616930
157 + 31616773 = 31616930
181 + 31616749 = 31616930
223 + 31616707 = 31616930
283 + 31616647 = 31616930
307 + 31616623 = 31616930

Showing the first eight; more decompositions exist.
