Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459744, here are decompositions:

11 + 31459733 = 31459744
47 + 31459697 = 31459744
83 + 31459661 = 31459744
191 + 31459553 = 31459744
227 + 31459517 = 31459744
257 + 31459487 = 31459744
311 + 31459433 = 31459744
401 + 31459343 = 31459744

Showing the first eight; more decompositions exist.
