Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616404, here are decompositions:

3 + 31616401 = 31616404
11 + 31616393 = 31616404
23 + 31616381 = 31616404
41 + 31616363 = 31616404
107 + 31616297 = 31616404
173 + 31616231 = 31616404
383 + 31616021 = 31616404
431 + 31615973 = 31616404

Showing the first eight; more decompositions exist.
