Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678512, here are decompositions:

  • 5 + 8678507 = 8678512
  • 113 + 8678399 = 8678512
  • 149 + 8678363 = 8678512
  • 173 + 8678339 = 8678512
  • 179 + 8678333 = 8678512
  • 383 + 8678129 = 8678512
  • 419 + 8678093 = 8678512
  • 431 + 8678081 = 8678512

Showing the first eight; more decompositions exist.
