Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546150, here are decompositions:

  • 131 + 31546019 = 31546150
  • 137 + 31546013 = 31546150
  • 191 + 31545959 = 31546150
  • 197 + 31545953 = 31546150
  • 227 + 31545923 = 31546150
  • 263 + 31545887 = 31546150
  • 401 + 31545749 = 31546150
  • 509 + 31545641 = 31546150

Showing the first eight; more decompositions exist.
