Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614490, here are decompositions:

41 + 31614449 = 31614490
113 + 31614377 = 31614490
137 + 31614353 = 31614490
263 + 31614227 = 31614490
293 + 31614197 = 31614490
311 + 31614179 = 31614490
317 + 31614173 = 31614490
419 + 31614071 = 31614490

Showing the first eight; more decompositions exist.
