Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529218, here are decompositions:

5 + 31529213 = 31529218
131 + 31529087 = 31529218
137 + 31529081 = 31529218
251 + 31528967 = 31529218
467 + 31528751 = 31529218
521 + 31528697 = 31529218
659 + 31528559 = 31529218
719 + 31528499 = 31529218

Showing the first eight; more decompositions exist.
