Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529278, here are decompositions:

5 + 31529273 = 31529278
29 + 31529249 = 31529278
59 + 31529219 = 31529278
191 + 31529087 = 31529278
197 + 31529081 = 31529278
281 + 31528997 = 31529278
311 + 31528967 = 31529278
467 + 31528811 = 31529278

Showing the first eight; more decompositions exist.
