Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42738, here are decompositions:

  • 11 + 42727 = 42738
  • 19 + 42719 = 42738
  • 29 + 42709 = 42738
  • 37 + 42701 = 42738
  • 41 + 42697 = 42738
  • 61 + 42677 = 42738
  • 71 + 42667 = 42738
  • 89 + 42649 = 42738

Showing the first eight; more decompositions exist.
