Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529146, here are decompositions:

59 + 31529087 = 31529146
149 + 31528997 = 31529146
179 + 31528967 = 31529146
293 + 31528853 = 31529146
449 + 31528697 = 31529146
587 + 31528559 = 31529146
599 + 31528547 = 31529146
647 + 31528499 = 31529146

Showing the first eight; more decompositions exist.
