Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533946, here are decompositions:

  • 23 + 31533923 = 31533946
  • 107 + 31533839 = 31533946
  • 113 + 31533833 = 31533946
  • 173 + 31533773 = 31533946
  • 239 + 31533707 = 31533946
  • 347 + 31533599 = 31533946
  • 359 + 31533587 = 31533946
  • 383 + 31533563 = 31533946

Showing the first eight; more decompositions exist.
