Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525436, here are decompositions:

  • 157 + 31525279 = 31525436
  • 193 + 31525243 = 31525436
  • 223 + 31525213 = 31525436
  • 409 + 31525027 = 31525436
  • 499 + 31524937 = 31525436
  • 643 + 31524793 = 31525436
  • 673 + 31524763 = 31525436
  • 829 + 31524607 = 31525436

Showing the first eight; more decompositions exist.
