Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483784, here are decompositions:

  • 61 + 31483723 = 31483784
  • 313 + 31483471 = 31483784
  • 331 + 31483453 = 31483784
  • 337 + 31483447 = 31483784
  • 433 + 31483351 = 31483784
  • 457 + 31483327 = 31483784
  • 523 + 31483261 = 31483784
  • 547 + 31483237 = 31483784

Showing the first eight; more decompositions exist.
