Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459516, here are decompositions:

17 + 31459499 = 31459516
29 + 31459487 = 31459516
59 + 31459457 = 31459516
83 + 31459433 = 31459516
107 + 31459409 = 31459516
167 + 31459349 = 31459516
173 + 31459343 = 31459516
227 + 31459289 = 31459516

Showing the first eight; more decompositions exist.
