Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459684, here are decompositions:

5 + 31459679 = 31459684
17 + 31459667 = 31459684
23 + 31459661 = 31459684
131 + 31459553 = 31459684
167 + 31459517 = 31459684
197 + 31459487 = 31459684
227 + 31459457 = 31459684
251 + 31459433 = 31459684

Showing the first eight; more decompositions exist.
