Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536320, here are decompositions:

  • 7 + 31536313 = 31536320
  • 97 + 31536223 = 31536320
  • 223 + 31536097 = 31536320
  • 271 + 31536049 = 31536320
  • 337 + 31535983 = 31536320
  • 373 + 31535947 = 31536320
  • 379 + 31535941 = 31536320
  • 499 + 31535821 = 31536320

Showing the first eight; more decompositions exist.
