Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627280, here are decompositions:

  • 23 + 8627257 = 8627280
  • 29 + 8627251 = 8627280
  • 37 + 8627243 = 8627280
  • 89 + 8627191 = 8627280
  • 107 + 8627173 = 8627280
  • 113 + 8627167 = 8627280
  • 127 + 8627153 = 8627280
  • 131 + 8627149 = 8627280

Showing the first eight; more decompositions exist.
