Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556710, here are decompositions:

  • 23 + 31556687 = 31556710
  • 71 + 31556639 = 31556710
  • 173 + 31556537 = 31556710
  • 233 + 31556477 = 31556710
  • 293 + 31556417 = 31556710
  • 401 + 31556309 = 31556710
  • 431 + 31556279 = 31556710
  • 461 + 31556249 = 31556710

Showing the first eight; more decompositions exist.
