Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750780, here are decompositions:

  • 19 + 8750761 = 8750780
  • 43 + 8750737 = 8750780
  • 61 + 8750719 = 8750780
  • 67 + 8750713 = 8750780
  • 79 + 8750701 = 8750780
  • 139 + 8750641 = 8750780
  • 229 + 8750551 = 8750780
  • 271 + 8750509 = 8750780

Showing the first eight; more decompositions exist.
