Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615704, here are decompositions:

41 + 31615663 = 31615704
53 + 31615651 = 31615704
101 + 31615603 = 31615704
227 + 31615477 = 31615704
233 + 31615471 = 31615704
313 + 31615391 = 31615704
383 + 31615321 = 31615704
431 + 31615273 = 31615704

Showing the first eight; more decompositions exist.
