Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473318, here are decompositions:

  • 17 + 2147473301 = 2147473318
  • 101 + 2147473217 = 2147473318
  • 131 + 2147473187 = 2147473318
  • 167 + 2147473151 = 2147473318
  • 191 + 2147473127 = 2147473318
  • 197 + 2147473121 = 2147473318
  • 257 + 2147473061 = 2147473318
  • 269 + 2147473049 = 2147473318

Showing the first eight; more decompositions exist.
