Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459514, here are decompositions:

127 + 31459387 = 31459514
157 + 31459357 = 31459514
193 + 31459321 = 31459514
223 + 31459291 = 31459514
313 + 31459201 = 31459514
421 + 31459093 = 31459514
547 + 31458967 = 31459514
577 + 31458937 = 31459514

Showing the first eight; more decompositions exist.
