Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750720, here are decompositions:

  • 7 + 8750713 = 8750720
  • 19 + 8750701 = 8750720
  • 31 + 8750689 = 8750720
  • 79 + 8750641 = 8750720
  • 193 + 8750527 = 8750720
  • 211 + 8750509 = 8750720
  • 229 + 8750491 = 8750720
  • 241 + 8750479 = 8750720

Showing the first eight; more decompositions exist.
