Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446022, here are decompositions:

  • 11 + 31446011 = 31446022
  • 131 + 31445891 = 31446022
  • 173 + 31445849 = 31446022
  • 233 + 31445789 = 31446022
  • 359 + 31445663 = 31446022
  • 401 + 31445621 = 31446022
  • 449 + 31445573 = 31446022
  • 479 + 31445543 = 31446022

Showing the first eight; more decompositions exist.
