Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534456, here are decompositions:

  • 29 + 31534427 = 31534456
  • 113 + 31534343 = 31534456
  • 257 + 31534199 = 31534456
  • 269 + 31534187 = 31534456
  • 353 + 31534103 = 31534456
  • 383 + 31534073 = 31534456
  • 389 + 31534067 = 31534456
  • 617 + 31533839 = 31534456

Showing the first eight; more decompositions exist.
