Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559050, here are decompositions:

  • 23 + 31559027 = 31559050
  • 53 + 31558997 = 31559050
  • 167 + 31558883 = 31559050
  • 191 + 31558859 = 31559050
  • 227 + 31558823 = 31559050
  • 251 + 31558799 = 31559050
  • 317 + 31558733 = 31559050
  • 401 + 31558649 = 31559050

Showing the first eight; more decompositions exist.
