Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616304, here are decompositions:

7 + 31616297 = 31616304
17 + 31616287 = 31616304
23 + 31616281 = 31616304
43 + 31616261 = 31616304
47 + 31616257 = 31616304
53 + 31616251 = 31616304
73 + 31616231 = 31616304
131 + 31616173 = 31616304

Showing the first eight; more decompositions exist.
