Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499034, here are decompositions:

11 + 31499023 = 31499034
13 + 31499021 = 31499034
31 + 31499003 = 31499034
41 + 31498993 = 31499034
43 + 31498991 = 31499034
67 + 31498967 = 31499034
71 + 31498963 = 31499034
103 + 31498931 = 31499034

Showing the first eight; more decompositions exist.
