Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678466, here are decompositions:

  • 19 + 8678447 = 8678466
  • 67 + 8678399 = 8678466
  • 73 + 8678393 = 8678466
  • 103 + 8678363 = 8678466
  • 107 + 8678359 = 8678466
  • 113 + 8678353 = 8678466
  • 127 + 8678339 = 8678466
  • 229 + 8678237 = 8678466

Showing the first eight; more decompositions exist.
