Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499332, here are decompositions:

  • 3 + 31499329 = 31499332
  • 5 + 31499327 = 31499332
  • 23 + 31499309 = 31499332
  • 41 + 31499291 = 31499332
  • 101 + 31499231 = 31499332
  • 149 + 31499183 = 31499332
  • 173 + 31499159 = 31499332
  • 269 + 31499063 = 31499332

Showing the first eight; more decompositions exist.
