Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499514, here are decompositions:

17 + 31499497 = 31499514
23 + 31499491 = 31499514
47 + 31499467 = 31499514
83 + 31499431 = 31499514
103 + 31499411 = 31499514
107 + 31499407 = 31499514
113 + 31499401 = 31499514
127 + 31499387 = 31499514

Showing the first eight; more decompositions exist.
