Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459606, here are decompositions:

53 + 31459553 = 31459606
89 + 31459517 = 31459606
107 + 31459499 = 31459606
149 + 31459457 = 31459606
173 + 31459433 = 31459606
197 + 31459409 = 31459606
257 + 31459349 = 31459606
263 + 31459343 = 31459606

Showing the first eight; more decompositions exist.
