Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546080, here are decompositions:

  • 11 + 31546069 = 31546080
  • 17 + 31546063 = 31546080
  • 61 + 31546019 = 31546080
  • 67 + 31546013 = 31546080
  • 73 + 31546007 = 31546080
  • 89 + 31545991 = 31546080
  • 127 + 31545953 = 31546080
  • 157 + 31545923 = 31546080

Showing the first eight; more decompositions exist.
