Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661130, here are decompositions:

  • 11 + 8661119 = 8661130
  • 41 + 8661089 = 8661130
  • 83 + 8661047 = 8661130
  • 197 + 8660933 = 8661130
  • 239 + 8660891 = 8661130
  • 311 + 8660819 = 8661130
  • 383 + 8660747 = 8661130
  • 389 + 8660741 = 8661130

Showing the first eight; more decompositions exist.
