Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672790, here are decompositions:

  • 11 + 8672779 = 8672790
  • 17 + 8672773 = 8672790
  • 23 + 8672767 = 8672790
  • 59 + 8672731 = 8672790
  • 67 + 8672723 = 8672790
  • 83 + 8672707 = 8672790
  • 103 + 8672687 = 8672790
  • 131 + 8672659 = 8672790

Showing the first eight; more decompositions exist.
