Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499446, here are decompositions:

  • 47 + 31499399 = 31499446
  • 59 + 31499387 = 31499446
  • 137 + 31499309 = 31499446
  • 149 + 31499297 = 31499446
  • 179 + 31499267 = 31499446
  • 257 + 31499189 = 31499446
  • 263 + 31499183 = 31499446
  • 383 + 31499063 = 31499446

Showing the first eight; more decompositions exist.
