Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125668, here are decompositions:

  • 17 + 125651 = 125668
  • 29 + 125639 = 125668
  • 41 + 125627 = 125668
  • 47 + 125621 = 125668
  • 71 + 125597 = 125668
  • 197 + 125471 = 125668
  • 227 + 125441 = 125668
  • 239 + 125429 = 125668

Showing the first eight; more decompositions exist.
