Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525882, here are decompositions:

  • 41 + 31525841 = 31525882
  • 71 + 31525811 = 31525882
  • 83 + 31525799 = 31525882
  • 233 + 31525649 = 31525882
  • 281 + 31525601 = 31525882
  • 293 + 31525589 = 31525882
  • 383 + 31525499 = 31525882
  • 461 + 31525421 = 31525882

Showing the first eight; more decompositions exist.
