Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78244, here are decompositions:

  • 3 + 78241 = 78244
  • 11 + 78233 = 78244
  • 41 + 78203 = 78244
  • 53 + 78191 = 78244
  • 71 + 78173 = 78244
  • 107 + 78137 = 78244
  • 227 + 78017 = 78244
  • 293 + 77951 = 78244

Showing the first eight; more decompositions exist.
