Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469618, here are decompositions:

  • 97 + 2147469521 = 2147469618
  • 127 + 2147469491 = 2147469618
  • 197 + 2147469421 = 2147469618
  • 199 + 2147469419 = 2147469618
  • 271 + 2147469347 = 2147469618
  • 347 + 2147469271 = 2147469618
  • 379 + 2147469239 = 2147469618
  • 389 + 2147469229 = 2147469618

Showing the first eight; more decompositions exist.
