Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517760, here are decompositions:

  • 13 + 517747 = 517760
  • 31 + 517729 = 517760
  • 43 + 517717 = 517760
  • 151 + 517609 = 517760
  • 157 + 517603 = 517760
  • 163 + 517597 = 517760
  • 211 + 517549 = 517760
  • 349 + 517411 = 517760

Showing the first eight; more decompositions exist.
