Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464450, here are decompositions:

  • 7 + 31464443 = 31464450
  • 11 + 31464439 = 31464450
  • 23 + 31464427 = 31464450
  • 29 + 31464421 = 31464450
  • 41 + 31464409 = 31464450
  • 53 + 31464397 = 31464450
  • 109 + 31464341 = 31464450
  • 179 + 31464271 = 31464450

Showing the first eight; more decompositions exist.
