Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525814, here are decompositions:

  • 3 + 31525811 = 31525814
  • 31 + 31525783 = 31525814
  • 37 + 31525777 = 31525814
  • 43 + 31525771 = 31525814
  • 97 + 31525717 = 31525814
  • 127 + 31525687 = 31525814
  • 157 + 31525657 = 31525814
  • 163 + 31525651 = 31525814

Showing the first eight; more decompositions exist.
