Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499422, here are decompositions:

11 + 31499411 = 31499422
23 + 31499399 = 31499422
113 + 31499309 = 31499422
131 + 31499291 = 31499422
191 + 31499231 = 31499422
233 + 31499189 = 31499422
239 + 31499183 = 31499422
263 + 31499159 = 31499422

Showing the first eight; more decompositions exist.
