Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499124, here are decompositions:

17 + 31499107 = 31499124
47 + 31499077 = 31499124
61 + 31499063 = 31499124
67 + 31499057 = 31499124
101 + 31499023 = 31499124
103 + 31499021 = 31499124
131 + 31498993 = 31499124
157 + 31498967 = 31499124

Showing the first eight; more decompositions exist.
