Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705690, here are decompositions:

  • 73 + 8705617 = 8705690
  • 79 + 8705611 = 8705690
  • 139 + 8705551 = 8705690
  • 163 + 8705527 = 8705690
  • 199 + 8705491 = 8705690
  • 223 + 8705467 = 8705690
  • 229 + 8705461 = 8705690
  • 241 + 8705449 = 8705690

Showing the first eight; more decompositions exist.
