Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42966, here are decompositions:

  • 5 + 42961 = 42966
  • 13 + 42953 = 42966
  • 23 + 42943 = 42966
  • 29 + 42937 = 42966
  • 37 + 42929 = 42966
  • 43 + 42923 = 42966
  • 67 + 42899 = 42966
  • 103 + 42863 = 42966

Showing the first eight; more decompositions exist.
