Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459522, here are decompositions:

5 + 31459517 = 31459522
23 + 31459499 = 31459522
89 + 31459433 = 31459522
113 + 31459409 = 31459522
173 + 31459349 = 31459522
179 + 31459343 = 31459522
233 + 31459289 = 31459522
389 + 31459133 = 31459522

Showing the first eight; more decompositions exist.
