Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529464, here are decompositions:

17 + 31529447 = 31529464
191 + 31529273 = 31529464
251 + 31529213 = 31529464
383 + 31529081 = 31529464
467 + 31528997 = 31529464
641 + 31528823 = 31529464
653 + 31528811 = 31529464
1013 + 31528451 = 31529464

Showing the first eight; more decompositions exist.
