Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716240, here are decompositions:

  • 3 + 8716237 = 8716240
  • 23 + 8716217 = 8716240
  • 53 + 8716187 = 8716240
  • 59 + 8716181 = 8716240
  • 89 + 8716151 = 8716240
  • 131 + 8716109 = 8716240
  • 179 + 8716061 = 8716240
  • 227 + 8716013 = 8716240

Showing the first eight; more decompositions exist.
