Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459564, here are decompositions:

11 + 31459553 = 31459564
23 + 31459541 = 31459564
47 + 31459517 = 31459564
107 + 31459457 = 31459564
131 + 31459433 = 31459564
347 + 31459217 = 31459564
431 + 31459133 = 31459564
491 + 31459073 = 31459564

Showing the first eight; more decompositions exist.
