Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661748, here are decompositions:

  • 5 + 8661743 = 8661748
  • 41 + 8661707 = 8661748
  • 59 + 8661689 = 8661748
  • 107 + 8661641 = 8661748
  • 167 + 8661581 = 8661748
  • 191 + 8661557 = 8661748
  • 239 + 8661509 = 8661748
  • 257 + 8661491 = 8661748

Showing the first eight; more decompositions exist.
