Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616410, here are decompositions:

17 + 31616393 = 31616410
29 + 31616381 = 31616410
41 + 31616369 = 31616410
47 + 31616363 = 31616410
71 + 31616339 = 31616410
83 + 31616327 = 31616410
113 + 31616297 = 31616410
149 + 31616261 = 31616410

Showing the first eight; more decompositions exist.
