Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607546, here are decompositions:

43 + 31607503 = 31607546
73 + 31607473 = 31607546
97 + 31607449 = 31607546
283 + 31607263 = 31607546
409 + 31607137 = 31607546
499 + 31607047 = 31607546
643 + 31606903 = 31607546
967 + 31606579 = 31607546

Showing the first eight; more decompositions exist.
