Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172776, here are decompositions:

  • 17 + 172759 = 172776
  • 59 + 172717 = 172776
  • 67 + 172709 = 172776
  • 89 + 172687 = 172776
  • 103 + 172673 = 172776
  • 113 + 172663 = 172776
  • 127 + 172649 = 172776
  • 157 + 172619 = 172776

Showing the first eight; more decompositions exist.
