Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673912, here are decompositions:

  • 11 + 8673901 = 8673912
  • 73 + 8673839 = 8673912
  • 131 + 8673781 = 8673912
  • 151 + 8673761 = 8673912
  • 229 + 8673683 = 8673912
  • 311 + 8673601 = 8673912
  • 449 + 8673463 = 8673912
  • 479 + 8673433 = 8673912

Showing the first eight; more decompositions exist.
