Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449524, here are decompositions:

  • 31 + 31449493 = 31449524
  • 61 + 31449463 = 31449524
  • 103 + 31449421 = 31449524
  • 151 + 31449373 = 31449524
  • 163 + 31449361 = 31449524
  • 277 + 31449247 = 31449524
  • 283 + 31449241 = 31449524
  • 397 + 31449127 = 31449524

Showing the first eight; more decompositions exist.
