Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459924, here are decompositions:

71 + 31459853 = 31459924
191 + 31459733 = 31459924
227 + 31459697 = 31459924
257 + 31459667 = 31459924
263 + 31459661 = 31459924
383 + 31459541 = 31459924
467 + 31459457 = 31459924
491 + 31459433 = 31459924

Showing the first eight; more decompositions exist.
