Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68280, here are decompositions:

  • 19 + 68261 = 68280
  • 41 + 68239 = 68280
  • 53 + 68227 = 68280
  • 61 + 68219 = 68280
  • 67 + 68213 = 68280
  • 71 + 68209 = 68280
  • 73 + 68207 = 68280
  • 109 + 68171 = 68280

Showing the first eight; more decompositions exist.
