Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529590, here are decompositions:

23 + 31529567 = 31529590
83 + 31529507 = 31529590
269 + 31529321 = 31529590
311 + 31529279 = 31529590
317 + 31529273 = 31529590
347 + 31529243 = 31529590
503 + 31529087 = 31529590
509 + 31529081 = 31529590

Showing the first eight; more decompositions exist.
