Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661692, here are decompositions:

  • 3 + 8661689 = 8661692
  • 19 + 8661673 = 8661692
  • 139 + 8661553 = 8661692
  • 163 + 8661529 = 8661692
  • 223 + 8661469 = 8661692
  • 439 + 8661253 = 8661692
  • 499 + 8661193 = 8661692
  • 631 + 8661061 = 8661692

Showing the first eight; more decompositions exist.
