Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499206, here are decompositions:

17 + 31499189 = 31499206
23 + 31499183 = 31499206
47 + 31499159 = 31499206
149 + 31499057 = 31499206
173 + 31499033 = 31499206
239 + 31498967 = 31499206
257 + 31498949 = 31499206
293 + 31498913 = 31499206

Showing the first eight; more decompositions exist.
