Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546072, here are decompositions:

  • 3 + 31546069 = 31546072
  • 53 + 31546019 = 31546072
  • 59 + 31546013 = 31546072
  • 113 + 31545959 = 31546072
  • 149 + 31545923 = 31546072
  • 359 + 31545713 = 31546072
  • 431 + 31545641 = 31546072
  • 443 + 31545629 = 31546072

Showing the first eight; more decompositions exist.
