Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42318, here are decompositions:

  • 11 + 42307 = 42318
  • 19 + 42299 = 42318
  • 37 + 42281 = 42318
  • 61 + 42257 = 42318
  • 79 + 42239 = 42318
  • 97 + 42221 = 42318
  • 109 + 42209 = 42318
  • 131 + 42187 = 42318

Showing the first eight; more decompositions exist.
