Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556584, here are decompositions:

  • 47 + 31556537 = 31556584
  • 83 + 31556501 = 31556584
  • 107 + 31556477 = 31556584
  • 167 + 31556417 = 31556584
  • 281 + 31556303 = 31556584
  • 383 + 31556201 = 31556584
  • 443 + 31556141 = 31556584
  • 503 + 31556081 = 31556584

Showing the first eight; more decompositions exist.
