Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525958, here are decompositions:

  • 7 + 31525951 = 31525958
  • 31 + 31525927 = 31525958
  • 67 + 31525891 = 31525958
  • 109 + 31525849 = 31525958
  • 181 + 31525777 = 31525958
  • 241 + 31525717 = 31525958
  • 271 + 31525687 = 31525958
  • 307 + 31525651 = 31525958

Showing the first eight; more decompositions exist.
