Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88690, here are decompositions:

  • 23 + 88667 = 88690
  • 29 + 88661 = 88690
  • 47 + 88643 = 88690
  • 83 + 88607 = 88690
  • 101 + 88589 = 88690
  • 167 + 88523 = 88690
  • 191 + 88499 = 88690
  • 197 + 88493 = 88690

Showing the first eight; more decompositions exist.
