Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86378, here are decompositions:

  • 7 + 86371 = 86378
  • 37 + 86341 = 86378
  • 67 + 86311 = 86378
  • 109 + 86269 = 86378
  • 139 + 86239 = 86378
  • 181 + 86197 = 86378
  • 199 + 86179 = 86378
  • 241 + 86137 = 86378

Showing the first eight; more decompositions exist.
