Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86272, here are decompositions:

  • 3 + 86269 = 86272
  • 23 + 86249 = 86272
  • 29 + 86243 = 86272
  • 71 + 86201 = 86272
  • 89 + 86183 = 86272
  • 101 + 86171 = 86272
  • 281 + 85991 = 86272
  • 383 + 85889 = 86272

Showing the first eight; more decompositions exist.
