Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525850, here are decompositions:

  • 67 + 31525783 = 31525850
  • 73 + 31525777 = 31525850
  • 79 + 31525771 = 31525850
  • 127 + 31525723 = 31525850
  • 151 + 31525699 = 31525850
  • 163 + 31525687 = 31525850
  • 193 + 31525657 = 31525850
  • 199 + 31525651 = 31525850

Showing the first eight; more decompositions exist.
