Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499950, here are decompositions:

11 + 31499939 = 31499950
17 + 31499933 = 31499950
29 + 31499921 = 31499950
107 + 31499843 = 31499950
239 + 31499711 = 31499950
389 + 31499561 = 31499950
491 + 31499459 = 31499950
563 + 31499387 = 31499950

Showing the first eight; more decompositions exist.
