Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525756, here are decompositions:

  • 107 + 31525649 = 31525756
  • 149 + 31525607 = 31525756
  • 167 + 31525589 = 31525756
  • 257 + 31525499 = 31525756
  • 359 + 31525397 = 31525756
  • 389 + 31525367 = 31525756
  • 467 + 31525289 = 31525756
  • 593 + 31525163 = 31525756

Showing the first eight; more decompositions exist.
