Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545056, here are decompositions:

  • 7 + 31545049 = 31545056
  • 157 + 31544899 = 31545056
  • 199 + 31544857 = 31545056
  • 229 + 31544827 = 31545056
  • 307 + 31544749 = 31545056
  • 337 + 31544719 = 31545056
  • 523 + 31544533 = 31545056
  • 547 + 31544509 = 31545056

Showing the first eight; more decompositions exist.
