Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508536, here are decompositions:

29 + 31508507 = 31508536
83 + 31508453 = 31508536
173 + 31508363 = 31508536
359 + 31508177 = 31508536
383 + 31508153 = 31508536
443 + 31508093 = 31508536
509 + 31508027 = 31508536
659 + 31507877 = 31508536

Showing the first eight; more decompositions exist.
