Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667620, here are decompositions:

  • 7 + 8667613 = 8667620
  • 19 + 8667601 = 8667620
  • 61 + 8667559 = 8667620
  • 109 + 8667511 = 8667620
  • 163 + 8667457 = 8667620
  • 193 + 8667427 = 8667620
  • 271 + 8667349 = 8667620
  • 307 + 8667313 = 8667620

Showing the first eight; more decompositions exist.
