Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469486, here are decompositions:

  • 23 + 2147469463 = 2147469486
  • 37 + 2147469449 = 2147469486
  • 67 + 2147469419 = 2147469486
  • 139 + 2147469347 = 2147469486
  • 157 + 2147469329 = 2147469486
  • 223 + 2147469263 = 2147469486
  • 257 + 2147469229 = 2147469486
  • 307 + 2147469179 = 2147469486

Showing the first eight; more decompositions exist.
