Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484680, here are decompositions:

  • 53 + 31484627 = 31484680
  • 137 + 31484543 = 31484680
  • 167 + 31484513 = 31484680
  • 263 + 31484417 = 31484680
  • 317 + 31484363 = 31484680
  • 443 + 31484237 = 31484680
  • 503 + 31484177 = 31484680
  • 587 + 31484093 = 31484680

Showing the first eight; more decompositions exist.
