Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545622, here are decompositions:

  • 11 + 31545611 = 31545622
  • 23 + 31545599 = 31545622
  • 293 + 31545329 = 31545622
  • 389 + 31545233 = 31545622
  • 401 + 31545221 = 31545622
  • 431 + 31545191 = 31545622
  • 503 + 31545119 = 31545622
  • 599 + 31545023 = 31545622

Showing the first eight; more decompositions exist.
