Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545698, here are decompositions:

  • 31 + 31545667 = 31545698
  • 199 + 31545499 = 31545698
  • 211 + 31545487 = 31545698
  • 229 + 31545469 = 31545698
  • 307 + 31545391 = 31545698
  • 367 + 31545331 = 31545698
  • 487 + 31545211 = 31545698
  • 601 + 31545097 = 31545698

Showing the first eight; more decompositions exist.
