Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534960, here are decompositions:

47 + 31534913 = 31534960
89 + 31534871 = 31534960
173 + 31534787 = 31534960
251 + 31534709 = 31534960
269 + 31534691 = 31534960
467 + 31534493 = 31534960
503 + 31534457 = 31534960
617 + 31534343 = 31534960

Showing the first eight; more decompositions exist.
