Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526012, here are decompositions:

  • 31 + 31525981 = 31526012
  • 61 + 31525951 = 31526012
  • 103 + 31525909 = 31526012
  • 109 + 31525903 = 31526012
  • 163 + 31525849 = 31526012
  • 229 + 31525783 = 31526012
  • 241 + 31525771 = 31526012
  • 313 + 31525699 = 31526012

Showing the first eight; more decompositions exist.
