Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544772, here are decompositions:

  • 13 + 31544759 = 31544772
  • 23 + 31544749 = 31544772
  • 53 + 31544719 = 31544772
  • 59 + 31544713 = 31544772
  • 199 + 31544573 = 31544772
  • 211 + 31544561 = 31544772
  • 229 + 31544543 = 31544772
  • 239 + 31544533 = 31544772

Showing the first eight; more decompositions exist.
