Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528516, here are decompositions:

  • 17 + 31528499 = 31528516
  • 83 + 31528433 = 31528516
  • 167 + 31528349 = 31528516
  • 179 + 31528337 = 31528516
  • 233 + 31528283 = 31528516
  • 347 + 31528169 = 31528516
  • 359 + 31528157 = 31528516
  • 389 + 31528127 = 31528516

Showing the first eight; more decompositions exist.
