Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494554, here are decompositions:

127 + 31494427 = 31494554
307 + 31494247 = 31494554
313 + 31494241 = 31494554
397 + 31494157 = 31494554
457 + 31494097 = 31494554
463 + 31494091 = 31494554
571 + 31493983 = 31494554
613 + 31493941 = 31494554

Showing the first eight; more decompositions exist.
