Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661146, here are decompositions:

  • 97 + 8661049 = 8661146
  • 103 + 8661043 = 8661146
  • 163 + 8660983 = 8661146
  • 199 + 8660947 = 8661146
  • 283 + 8660863 = 8661146
  • 349 + 8660797 = 8661146
  • 379 + 8660767 = 8661146
  • 457 + 8660689 = 8661146

Showing the first eight; more decompositions exist.
