Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66612, here are decompositions:

  • 11 + 66601 = 66612
  • 19 + 66593 = 66612
  • 41 + 66571 = 66612
  • 43 + 66569 = 66612
  • 59 + 66553 = 66612
  • 71 + 66541 = 66612
  • 79 + 66533 = 66612
  • 83 + 66529 = 66612

Showing the first eight; more decompositions exist.
