Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459524, here are decompositions:

7 + 31459517 = 31459524
37 + 31459487 = 31459524
67 + 31459457 = 31459524
137 + 31459387 = 31459524
167 + 31459357 = 31459524
181 + 31459343 = 31459524
233 + 31459291 = 31459524
263 + 31459261 = 31459524

Showing the first eight; more decompositions exist.
