Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82378, here are decompositions:

  • 5 + 82373 = 82378
  • 17 + 82361 = 82378
  • 29 + 82349 = 82378
  • 71 + 82307 = 82378
  • 137 + 82241 = 82378
  • 239 + 82139 = 82378
  • 311 + 82067 = 82378
  • 347 + 82031 = 82378

Showing the first eight; more decompositions exist.
