Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544806, here are decompositions:

  • 23 + 31544783 = 31544806
  • 47 + 31544759 = 31544806
  • 89 + 31544717 = 31544806
  • 149 + 31544657 = 31544806
  • 233 + 31544573 = 31544806
  • 263 + 31544543 = 31544806
  • 389 + 31544417 = 31544806
  • 443 + 31544363 = 31544806

Showing the first eight; more decompositions exist.
