Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544556, here are decompositions:

  • 5 + 31544551 = 31544556
  • 13 + 31544543 = 31544556
  • 23 + 31544533 = 31544556
  • 47 + 31544509 = 31544556
  • 139 + 31544417 = 31544556
  • 163 + 31544393 = 31544556
  • 193 + 31544363 = 31544556
  • 233 + 31544323 = 31544556

Showing the first eight; more decompositions exist.
