Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627690, here are decompositions:

  • 73 + 8627617 = 8627690
  • 79 + 8627611 = 8627690
  • 109 + 8627581 = 8627690
  • 157 + 8627533 = 8627690
  • 163 + 8627527 = 8627690
  • 193 + 8627497 = 8627690
  • 223 + 8627467 = 8627690
  • 349 + 8627341 = 8627690

Showing the first eight; more decompositions exist.
