Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508066, here are decompositions:

127 + 31507939 = 31508066
229 + 31507837 = 31508066
277 + 31507789 = 31508066
313 + 31507753 = 31508066
367 + 31507699 = 31508066
433 + 31507633 = 31508066
607 + 31507459 = 31508066
769 + 31507297 = 31508066

Showing the first eight; more decompositions exist.
