Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525748, here are decompositions:

  • 31 + 31525717 = 31525748
  • 61 + 31525687 = 31525748
  • 97 + 31525651 = 31525748
  • 139 + 31525609 = 31525748
  • 181 + 31525567 = 31525748
  • 211 + 31525537 = 31525748
  • 271 + 31525477 = 31525748
  • 487 + 31525261 = 31525748

Showing the first eight; more decompositions exist.
