Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493998, here are decompositions:

47 + 31493951 = 31493998
71 + 31493927 = 31493998
89 + 31493909 = 31493998
281 + 31493717 = 31493998
479 + 31493519 = 31493998
521 + 31493477 = 31493998
659 + 31493339 = 31493998
677 + 31493321 = 31493998

Showing the first eight; more decompositions exist.
