Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499296, here are decompositions:

5 + 31499291 = 31499296
29 + 31499267 = 31499296
107 + 31499189 = 31499296
113 + 31499183 = 31499296
137 + 31499159 = 31499296
233 + 31499063 = 31499296
239 + 31499057 = 31499296
263 + 31499033 = 31499296

Showing the first eight; more decompositions exist.
