Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147443326, here are decompositions:

  • 23 + 2147443303 = 2147443326
  • 43 + 2147443283 = 2147443326
  • 103 + 2147443223 = 2147443326
  • 157 + 2147443169 = 2147443326
  • 163 + 2147443163 = 2147443326
  • 239 + 2147443087 = 2147443326
  • 269 + 2147443057 = 2147443326
  • 277 + 2147443049 = 2147443326

Showing the first eight; more decompositions exist.
