Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 112842, here are decompositions:

  • 11 + 112831 = 112842
  • 43 + 112799 = 112842
  • 71 + 112771 = 112842
  • 83 + 112759 = 112842
  • 101 + 112741 = 112842
  • 151 + 112691 = 112842
  • 179 + 112663 = 112842
  • 199 + 112643 = 112842

Showing the first eight; more decompositions exist.
