Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494506, here are decompositions:

3 + 31494503 = 31494506
37 + 31494469 = 31494506
67 + 31494439 = 31494506
79 + 31494427 = 31494506
349 + 31494157 = 31494506
409 + 31494097 = 31494506
523 + 31493983 = 31494506
607 + 31493899 = 31494506

Showing the first eight; more decompositions exist.
