Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616412, here are decompositions:

11 + 31616401 = 31616412
19 + 31616393 = 31616412
31 + 31616381 = 31616412
43 + 31616369 = 31616412
53 + 31616359 = 31616412
73 + 31616339 = 31616412
131 + 31616281 = 31616412
151 + 31616261 = 31616412

Showing the first eight; more decompositions exist.
