Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635680, here are decompositions:

  • 7 + 8635673 = 8635680
  • 13 + 8635667 = 8635680
  • 17 + 8635663 = 8635680
  • 23 + 8635657 = 8635680
  • 43 + 8635637 = 8635680
  • 59 + 8635621 = 8635680
  • 73 + 8635607 = 8635680
  • 101 + 8635579 = 8635680

Showing the first eight; more decompositions exist.
