Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469494, here are decompositions:

  • 3 + 2147469491 = 2147469494
  • 31 + 2147469463 = 2147469494
  • 73 + 2147469421 = 2147469494
  • 211 + 2147469283 = 2147469494
  • 223 + 2147469271 = 2147469494
  • 307 + 2147469187 = 2147469494
  • 337 + 2147469157 = 2147469494
  • 421 + 2147469073 = 2147469494

Showing the first eight; more decompositions exist.
