Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525632, here are decompositions:

  • 23 + 31525609 = 31525632
  • 29 + 31525603 = 31525632
  • 31 + 31525601 = 31525632
  • 43 + 31525589 = 31525632
  • 79 + 31525553 = 31525632
  • 211 + 31525421 = 31525632
  • 349 + 31525283 = 31525632
  • 353 + 31525279 = 31525632

Showing the first eight; more decompositions exist.
