Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525804, here are decompositions:

  • 5 + 31525799 = 31525804
  • 17 + 31525787 = 31525804
  • 41 + 31525763 = 31525804
  • 197 + 31525607 = 31525804
  • 251 + 31525553 = 31525804
  • 383 + 31525421 = 31525804
  • 461 + 31525343 = 31525804
  • 521 + 31525283 = 31525804

Showing the first eight; more decompositions exist.
