Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525736, here are decompositions:

  • 13 + 31525723 = 31525736
  • 19 + 31525717 = 31525736
  • 37 + 31525699 = 31525736
  • 79 + 31525657 = 31525736
  • 127 + 31525609 = 31525736
  • 199 + 31525537 = 31525736
  • 457 + 31525279 = 31525736
  • 523 + 31525213 = 31525736

Showing the first eight; more decompositions exist.
