Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7966, here are decompositions:

  • 3 + 7963 = 7966
  • 17 + 7949 = 7966
  • 29 + 7937 = 7966
  • 47 + 7919 = 7966
  • 59 + 7907 = 7966
  • 83 + 7883 = 7966
  • 89 + 7877 = 7966
  • 113 + 7853 = 7966

Showing the first eight; more decompositions exist.
