Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556764, here are decompositions:

  • 17 + 31556747 = 31556764
  • 23 + 31556741 = 31556764
  • 227 + 31556537 = 31556764
  • 263 + 31556501 = 31556764
  • 347 + 31556417 = 31556764
  • 383 + 31556381 = 31556764
  • 461 + 31556303 = 31556764
  • 521 + 31556243 = 31556764

Showing the first eight; more decompositions exist.
