Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529794, here are decompositions:

11 + 31529783 = 31529794
113 + 31529681 = 31529794
227 + 31529567 = 31529794
347 + 31529447 = 31529794
521 + 31529273 = 31529794
797 + 31528997 = 31529794
827 + 31528967 = 31529794
941 + 31528853 = 31529794

Showing the first eight; more decompositions exist.
