Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525874, here are decompositions:

  • 97 + 31525777 = 31525874
  • 103 + 31525771 = 31525874
  • 151 + 31525723 = 31525874
  • 157 + 31525717 = 31525874
  • 223 + 31525651 = 31525874
  • 271 + 31525603 = 31525874
  • 307 + 31525567 = 31525874
  • 337 + 31525537 = 31525874

Showing the first eight; more decompositions exist.
