Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560512, here are decompositions:

  • 3 + 31560509 = 31560512
  • 13 + 31560499 = 31560512
  • 43 + 31560469 = 31560512
  • 79 + 31560433 = 31560512
  • 433 + 31560079 = 31560512
  • 439 + 31560073 = 31560512
  • 523 + 31559989 = 31560512
  • 601 + 31559911 = 31560512

Showing the first eight; more decompositions exist.
