Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469384, here are decompositions:

  • 37 + 2147469347 = 2147469384
  • 101 + 2147469283 = 2147469384
  • 113 + 2147469271 = 2147469384
  • 197 + 2147469187 = 2147469384
  • 211 + 2147469173 = 2147469384
  • 227 + 2147469157 = 2147469384
  • 251 + 2147469133 = 2147469384
  • 271 + 2147469113 = 2147469384

Showing the first eight; more decompositions exist.
