Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607632, here are decompositions:

3 + 31607629 = 31607632
53 + 31607579 = 31607632
101 + 31607531 = 31607632
233 + 31607399 = 31607632
269 + 31607363 = 31607632
431 + 31607201 = 31607632
479 + 31607153 = 31607632
593 + 31607039 = 31607632

Showing the first eight; more decompositions exist.
