Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3680, here are decompositions:

  • 3 + 3677 = 3680
  • 7 + 3673 = 3680
  • 37 + 3643 = 3680
  • 43 + 3637 = 3680
  • 67 + 3613 = 3680
  • 73 + 3607 = 3680
  • 97 + 3583 = 3680
  • 109 + 3571 = 3680

Showing the first eight; more decompositions exist.
