Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499874, here are decompositions:

11 + 31499863 = 31499874
31 + 31499843 = 31499874
41 + 31499833 = 31499874
71 + 31499803 = 31499874
113 + 31499761 = 31499874
163 + 31499711 = 31499874
281 + 31499593 = 31499874
313 + 31499561 = 31499874

Showing the first eight; more decompositions exist.
