Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616818, here are decompositions:

  • 37 + 8616781 = 8616818
  • 61 + 8616757 = 8616818
  • 97 + 8616721 = 8616818
  • 127 + 8616691 = 8616818
  • 139 + 8616679 = 8616818
  • 157 + 8616661 = 8616818
  • 271 + 8616547 = 8616818
  • 277 + 8616541 = 8616818

Showing the first eight; more decompositions exist.
