Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529812, here are decompositions:

29 + 31529783 = 31529812
131 + 31529681 = 31529812
491 + 31529321 = 31529812
563 + 31529249 = 31529812
569 + 31529243 = 31529812
593 + 31529219 = 31529812
599 + 31529213 = 31529812
971 + 31528841 = 31529812

Showing the first eight; more decompositions exist.
