Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499456, here are decompositions:

73 + 31499383 = 31499456
127 + 31499329 = 31499456
229 + 31499227 = 31499456
349 + 31499107 = 31499456
379 + 31499077 = 31499456
433 + 31499023 = 31499456
463 + 31498993 = 31499456
577 + 31498879 = 31499456

Showing the first eight; more decompositions exist.
