Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535536, here are decompositions:

  • 107 + 31535429 = 31535536
  • 113 + 31535423 = 31535536
  • 317 + 31535219 = 31535536
  • 353 + 31535183 = 31535536
  • 479 + 31535057 = 31535536
  • 503 + 31535033 = 31535536
  • 797 + 31534739 = 31535536
  • 827 + 31534709 = 31535536

Showing the first eight; more decompositions exist.
