Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459546, here are decompositions:

5 + 31459541 = 31459546
29 + 31459517 = 31459546
47 + 31459499 = 31459546
59 + 31459487 = 31459546
89 + 31459457 = 31459546
113 + 31459433 = 31459546
137 + 31459409 = 31459546
197 + 31459349 = 31459546

Showing the first eight; more decompositions exist.
