Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529506, here are decompositions:

59 + 31529447 = 31529506
227 + 31529279 = 31529506
233 + 31529273 = 31529506
257 + 31529249 = 31529506
263 + 31529243 = 31529506
293 + 31529213 = 31529506
419 + 31529087 = 31529506
509 + 31528997 = 31529506

Showing the first eight; more decompositions exist.
