Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501466, here are decompositions:

19 + 31501447 = 31501466
67 + 31501399 = 31501466
79 + 31501387 = 31501466
163 + 31501303 = 31501466
349 + 31501117 = 31501466
457 + 31501009 = 31501466
487 + 31500979 = 31501466
499 + 31500967 = 31501466

Showing the first eight; more decompositions exist.
