Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475952, here are decompositions:

  • 23 + 31475929 = 31475952
  • 41 + 31475911 = 31475952
  • 43 + 31475909 = 31475952
  • 103 + 31475849 = 31475952
  • 139 + 31475813 = 31475952
  • 173 + 31475779 = 31475952
  • 181 + 31475771 = 31475952
  • 239 + 31475713 = 31475952

Showing the first eight; more decompositions exist.
