Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508632, here are decompositions:

11 + 31508621 = 31508632
53 + 31508579 = 31508632
83 + 31508549 = 31508632
179 + 31508453 = 31508632
269 + 31508363 = 31508632
401 + 31508231 = 31508632
461 + 31508171 = 31508632
479 + 31508153 = 31508632

Showing the first eight; more decompositions exist.
