Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508962, here are decompositions:

3 + 31508959 = 31508962
41 + 31508921 = 31508962
281 + 31508681 = 31508962
311 + 31508651 = 31508962
383 + 31508579 = 31508962
509 + 31508453 = 31508962
599 + 31508363 = 31508962
809 + 31508153 = 31508962

Showing the first eight; more decompositions exist.
