Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494374, here are decompositions:

73 + 31494301 = 31494374
127 + 31494247 = 31494374
277 + 31494097 = 31494374
283 + 31494091 = 31494374
433 + 31493941 = 31494374
523 + 31493851 = 31494374
631 + 31493743 = 31494374
733 + 31493641 = 31494374

Showing the first eight; more decompositions exist.
