Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691512, here are decompositions:

  • 3 + 8691509 = 8691512
  • 31 + 8691481 = 8691512
  • 43 + 8691469 = 8691512
  • 61 + 8691451 = 8691512
  • 79 + 8691433 = 8691512
  • 139 + 8691373 = 8691512
  • 199 + 8691313 = 8691512
  • 283 + 8691229 = 8691512

Showing the first eight; more decompositions exist.
