Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529588, here are decompositions:

31 + 31529557 = 31529588
37 + 31529551 = 31529588
67 + 31529521 = 31529588
109 + 31529479 = 31529588
157 + 31529431 = 31529588
229 + 31529359 = 31529588
241 + 31529347 = 31529588
331 + 31529257 = 31529588

Showing the first eight; more decompositions exist.
