Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690742, here are decompositions:

  • 29 + 8690713 = 8690742
  • 59 + 8690683 = 8690742
  • 79 + 8690663 = 8690742
  • 83 + 8690659 = 8690742
  • 103 + 8690639 = 8690742
  • 131 + 8690611 = 8690742
  • 139 + 8690603 = 8690742
  • 149 + 8690593 = 8690742

Showing the first eight; more decompositions exist.
