Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647770, here are decompositions:

  • 11 + 8647759 = 8647770
  • 17 + 8647753 = 8647770
  • 31 + 8647739 = 8647770
  • 59 + 8647711 = 8647770
  • 71 + 8647699 = 8647770
  • 73 + 8647697 = 8647770
  • 113 + 8647657 = 8647770
  • 181 + 8647589 = 8647770

Showing the first eight; more decompositions exist.
