Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459584, here are decompositions:

31 + 31459553 = 31459584
43 + 31459541 = 31459584
67 + 31459517 = 31459584
97 + 31459487 = 31459584
127 + 31459457 = 31459584
151 + 31459433 = 31459584
197 + 31459387 = 31459584
227 + 31459357 = 31459584

Showing the first eight; more decompositions exist.
