Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527456, here are decompositions:

  • 43 + 31527413 = 31527456
  • 67 + 31527389 = 31527456
  • 113 + 31527343 = 31527456
  • 139 + 31527317 = 31527456
  • 179 + 31527277 = 31527456
  • 223 + 31527233 = 31527456
  • 263 + 31527193 = 31527456
  • 283 + 31527173 = 31527456

Showing the first eight; more decompositions exist.
