Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501456, here are decompositions:

  • 13 + 2147501443 = 2147501456
  • 19 + 2147501437 = 2147501456
  • 223 + 2147501233 = 2147501456
  • 283 + 2147501173 = 2147501456
  • 313 + 2147501143 = 2147501456
  • 367 + 2147501089 = 2147501456
  • 379 + 2147501077 = 2147501456
  • 547 + 2147500909 = 2147501456

Showing the first eight; more decompositions exist.
