Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42668, here are decompositions:

  • 19 + 42649 = 42668
  • 79 + 42589 = 42668
  • 97 + 42571 = 42668
  • 181 + 42487 = 42668
  • 211 + 42457 = 42668
  • 271 + 42397 = 42668
  • 277 + 42391 = 42668
  • 331 + 42337 = 42668

Showing the first eight; more decompositions exist.
