Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529284, here are decompositions:

5 + 31529279 = 31529284
11 + 31529273 = 31529284
41 + 31529243 = 31529284
71 + 31529213 = 31529284
197 + 31529087 = 31529284
317 + 31528967 = 31529284
431 + 31528853 = 31529284
443 + 31528841 = 31529284

Showing the first eight; more decompositions exist.
