Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546186, here are decompositions:

  • 5 + 31546181 = 31546186
  • 167 + 31546019 = 31546186
  • 173 + 31546013 = 31546186
  • 179 + 31546007 = 31546186
  • 227 + 31545959 = 31546186
  • 233 + 31545953 = 31546186
  • 263 + 31545923 = 31546186
  • 443 + 31545743 = 31546186

Showing the first eight; more decompositions exist.
