Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508504, here are decompositions:

43 + 31508461 = 31508504
61 + 31508443 = 31508504
193 + 31508311 = 31508504
271 + 31508233 = 31508504
277 + 31508227 = 31508504
397 + 31508107 = 31508504
421 + 31508083 = 31508504
487 + 31508017 = 31508504

Showing the first eight; more decompositions exist.
