Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499326, here are decompositions:

3 + 31499323 = 31499326
17 + 31499309 = 31499326
29 + 31499297 = 31499326
59 + 31499267 = 31499326
137 + 31499189 = 31499326
167 + 31499159 = 31499326
263 + 31499063 = 31499326
269 + 31499057 = 31499326

Showing the first eight; more decompositions exist.
