Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525782, here are decompositions:

  • 5 + 31525777 = 31525782
  • 11 + 31525771 = 31525782
  • 19 + 31525763 = 31525782
  • 59 + 31525723 = 31525782
  • 83 + 31525699 = 31525782
  • 131 + 31525651 = 31525782
  • 173 + 31525609 = 31525782
  • 179 + 31525603 = 31525782

Showing the first eight; more decompositions exist.
