Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529584, here are decompositions:

17 + 31529567 = 31529584
113 + 31529471 = 31529584
137 + 31529447 = 31529584
263 + 31529321 = 31529584
311 + 31529273 = 31529584
503 + 31529081 = 31529584
587 + 31528997 = 31529584
617 + 31528967 = 31529584

Showing the first eight; more decompositions exist.
