Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689730, here are decompositions:

  • 3 + 8689727 = 8689730
  • 19 + 8689711 = 8689730
  • 43 + 8689687 = 8689730
  • 73 + 8689657 = 8689730
  • 103 + 8689627 = 8689730
  • 139 + 8689591 = 8689730
  • 157 + 8689573 = 8689730
  • 193 + 8689537 = 8689730

Showing the first eight; more decompositions exist.
