Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697778, here are decompositions:

  • 71 + 8697707 = 8697778
  • 101 + 8697677 = 8697778
  • 137 + 8697641 = 8697778
  • 179 + 8697599 = 8697778
  • 191 + 8697587 = 8697778
  • 197 + 8697581 = 8697778
  • 227 + 8697551 = 8697778
  • 239 + 8697539 = 8697778

Showing the first eight; more decompositions exist.
