Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499064, here are decompositions:

7 + 31499057 = 31499064
31 + 31499033 = 31499064
41 + 31499023 = 31499064
43 + 31499021 = 31499064
61 + 31499003 = 31499064
71 + 31498993 = 31499064
73 + 31498991 = 31499064
97 + 31498967 = 31499064

Showing the first eight; more decompositions exist.
