Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499304, here are decompositions:

7 + 31499297 = 31499304
13 + 31499291 = 31499304
37 + 31499267 = 31499304
73 + 31499231 = 31499304
167 + 31499137 = 31499304
197 + 31499107 = 31499304
227 + 31499077 = 31499304
241 + 31499063 = 31499304

Showing the first eight; more decompositions exist.
