Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501442, here are decompositions:

  • 5 + 2147501437 = 2147501442
  • 11 + 2147501431 = 2147501442
  • 139 + 2147501303 = 2147501442
  • 193 + 2147501249 = 2147501442
  • 269 + 2147501173 = 2147501442
  • 311 + 2147501131 = 2147501442
  • 313 + 2147501129 = 2147501442
  • 353 + 2147501089 = 2147501442

Showing the first eight; more decompositions exist.
