Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527412, here are decompositions:

  • 5 + 31527407 = 31527412
  • 23 + 31527389 = 31527412
  • 89 + 31527323 = 31527412
  • 101 + 31527311 = 31527412
  • 179 + 31527233 = 31527412
  • 239 + 31527173 = 31527412
  • 263 + 31527149 = 31527412
  • 269 + 31527143 = 31527412

Showing the first eight; more decompositions exist.
