Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84280, here are decompositions:

  • 17 + 84263 = 84280
  • 41 + 84239 = 84280
  • 59 + 84221 = 84280
  • 89 + 84191 = 84280
  • 101 + 84179 = 84280
  • 137 + 84143 = 84280
  • 149 + 84131 = 84280
  • 191 + 84089 = 84280

Showing the first eight; more decompositions exist.
