Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612520, here are decompositions:

  • 17 + 8612503 = 8612520
  • 23 + 8612497 = 8612520
  • 41 + 8612479 = 8612520
  • 47 + 8612473 = 8612520
  • 83 + 8612437 = 8612520
  • 97 + 8612423 = 8612520
  • 107 + 8612413 = 8612520
  • 109 + 8612411 = 8612520

Showing the first eight; more decompositions exist.
