Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499262, here are decompositions:

23 + 31499239 = 31499262
31 + 31499231 = 31499262
73 + 31499189 = 31499262
79 + 31499183 = 31499262
101 + 31499161 = 31499262
103 + 31499159 = 31499262
199 + 31499063 = 31499262
229 + 31499033 = 31499262

Showing the first eight; more decompositions exist.
