Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559506, here are decompositions:

5 + 31559501 = 31559506
59 + 31559447 = 31559506
89 + 31559417 = 31559506
317 + 31559189 = 31559506
479 + 31559027 = 31559506
509 + 31558997 = 31559506
647 + 31558859 = 31559506
659 + 31558847 = 31559506

Showing the first eight; more decompositions exist.
