Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525892, here are decompositions:

  • 3 + 31525889 = 31525892
  • 43 + 31525849 = 31525892
  • 109 + 31525783 = 31525892
  • 193 + 31525699 = 31525892
  • 241 + 31525651 = 31525892
  • 283 + 31525609 = 31525892
  • 613 + 31525279 = 31525892
  • 631 + 31525261 = 31525892

Showing the first eight; more decompositions exist.
