Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460440, here are decompositions:

  • 41 + 31460399 = 31460440
  • 71 + 31460369 = 31460440
  • 101 + 31460339 = 31460440
  • 149 + 31460291 = 31460440
  • 173 + 31460267 = 31460440
  • 311 + 31460129 = 31460440
  • 491 + 31459949 = 31460440
  • 503 + 31459937 = 31460440

Showing the first eight; more decompositions exist.
