Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661104, here are decompositions:

  • 43 + 8661061 = 8661104
  • 61 + 8661043 = 8661104
  • 103 + 8661001 = 8661104
  • 157 + 8660947 = 8661104
  • 241 + 8660863 = 8661104
  • 307 + 8660797 = 8661104
  • 337 + 8660767 = 8661104
  • 421 + 8660683 = 8661104

Showing the first eight; more decompositions exist.
