Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45642, here are decompositions:

  • 11 + 45631 = 45642
  • 29 + 45613 = 45642
  • 43 + 45599 = 45642
  • 53 + 45589 = 45642
  • 73 + 45569 = 45642
  • 89 + 45553 = 45642
  • 101 + 45541 = 45642
  • 109 + 45533 = 45642

Showing the first eight; more decompositions exist.
