Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538610, here are decompositions:

29 + 31538581 = 31538610
31 + 31538579 = 31538610
41 + 31538569 = 31538610
53 + 31538557 = 31538610
71 + 31538539 = 31538610
83 + 31538527 = 31538610
107 + 31538503 = 31538610
137 + 31538473 = 31538610

Showing the first eight; more decompositions exist.
