Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66510, here are decompositions:

  • 11 + 66499 = 66510
  • 19 + 66491 = 66510
  • 43 + 66467 = 66510
  • 47 + 66463 = 66510
  • 53 + 66457 = 66510
  • 61 + 66449 = 66510
  • 79 + 66431 = 66510
  • 97 + 66413 = 66510

Showing the first eight; more decompositions exist.
