Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86528, here are decompositions:

  • 19 + 86509 = 86528
  • 37 + 86491 = 86528
  • 61 + 86467 = 86528
  • 67 + 86461 = 86528
  • 139 + 86389 = 86528
  • 157 + 86371 = 86528
  • 241 + 86287 = 86528
  • 271 + 86257 = 86528

Showing the first eight; more decompositions exist.
