Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667672, here are decompositions:

  • 11 + 8667661 = 8667672
  • 19 + 8667653 = 8667672
  • 31 + 8667641 = 8667672
  • 59 + 8667613 = 8667672
  • 61 + 8667611 = 8667672
  • 71 + 8667601 = 8667672
  • 109 + 8667563 = 8667672
  • 113 + 8667559 = 8667672

Showing the first eight; more decompositions exist.
