Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529244, here are decompositions:

31 + 31529213 = 31529244
137 + 31529107 = 31529244
157 + 31529087 = 31529244
163 + 31529081 = 31529244
191 + 31529053 = 31529244
251 + 31528993 = 31529244
277 + 31528967 = 31529244
401 + 31528843 = 31529244

Showing the first eight; more decompositions exist.
