Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661008, here are decompositions:

  • 7 + 8661001 = 8661008
  • 61 + 8660947 = 8661008
  • 79 + 8660929 = 8661008
  • 211 + 8660797 = 8661008
  • 241 + 8660767 = 8661008
  • 337 + 8660671 = 8661008
  • 397 + 8660611 = 8661008
  • 439 + 8660569 = 8661008

Showing the first eight; more decompositions exist.
