Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476730, here are decompositions:

  • 3 + 31476727 = 31476730
  • 107 + 31476623 = 31476730
  • 137 + 31476593 = 31476730
  • 179 + 31476551 = 31476730
  • 269 + 31476461 = 31476730
  • 281 + 31476449 = 31476730
  • 293 + 31476437 = 31476730
  • 317 + 31476413 = 31476730

Showing the first eight; more decompositions exist.
