Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608286, here are decompositions:

  • 23 + 31608263 = 31608286
  • 137 + 31608149 = 31608286
  • 179 + 31608107 = 31608286
  • 239 + 31608047 = 31608286
  • 257 + 31608029 = 31608286
  • 317 + 31607969 = 31608286
  • 383 + 31607903 = 31608286
  • 389 + 31607897 = 31608286

Showing the first eight; more decompositions exist.
