Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13122, here are decompositions:

  • 13 + 13109 = 13122
  • 19 + 13103 = 13122
  • 23 + 13099 = 13122
  • 29 + 13093 = 13122
  • 59 + 13063 = 13122
  • 73 + 13049 = 13122
  • 79 + 13043 = 13122
  • 89 + 13033 = 13122

Showing the first eight; more decompositions exist.
