Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677812, here are decompositions:

  • 41 + 8677771 = 8677812
  • 53 + 8677759 = 8677812
  • 89 + 8677723 = 8677812
  • 131 + 8677681 = 8677812
  • 149 + 8677663 = 8677812
  • 331 + 8677481 = 8677812
  • 359 + 8677453 = 8677812
  • 419 + 8677393 = 8677812

Showing the first eight; more decompositions exist.
