Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499038, here are decompositions:

5 + 31499033 = 31499038
17 + 31499021 = 31499038
47 + 31498991 = 31499038
71 + 31498967 = 31499038
89 + 31498949 = 31499038
107 + 31498931 = 31499038
191 + 31498847 = 31499038
227 + 31498811 = 31499038

Showing the first eight; more decompositions exist.
