Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459612, here are decompositions:

3 + 31459609 = 31459612
59 + 31459553 = 31459612
71 + 31459541 = 31459612
113 + 31459499 = 31459612
179 + 31459433 = 31459612
263 + 31459349 = 31459612
269 + 31459343 = 31459612
389 + 31459223 = 31459612

Showing the first eight; more decompositions exist.
