Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79642, here are decompositions:

  • 11 + 79631 = 79642
  • 29 + 79613 = 79642
  • 41 + 79601 = 79642
  • 53 + 79589 = 79642
  • 83 + 79559 = 79642
  • 149 + 79493 = 79642
  • 191 + 79451 = 79642
  • 263 + 79379 = 79642

Showing the first eight; more decompositions exist.
