Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663886, here are decompositions:

  • 17 + 8663869 = 8663886
  • 59 + 8663827 = 8663886
  • 67 + 8663819 = 8663886
  • 79 + 8663807 = 8663886
  • 83 + 8663803 = 8663886
  • 89 + 8663797 = 8663886
  • 109 + 8663777 = 8663886
  • 167 + 8663719 = 8663886

Showing the first eight; more decompositions exist.
