Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528986, here are decompositions:

  • 17 + 31528969 = 31528986
  • 19 + 31528967 = 31528986
  • 163 + 31528823 = 31528986
  • 173 + 31528813 = 31528986
  • 179 + 31528807 = 31528986
  • 257 + 31528729 = 31528986
  • 263 + 31528723 = 31528986
  • 317 + 31528669 = 31528986

Showing the first eight; more decompositions exist.
