Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42620, here are decompositions:

  • 31 + 42589 = 42620
  • 43 + 42577 = 42620
  • 157 + 42463 = 42620
  • 163 + 42457 = 42620
  • 211 + 42409 = 42620
  • 223 + 42397 = 42620
  • 229 + 42391 = 42620
  • 241 + 42379 = 42620

Showing the first eight; more decompositions exist.
