Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147374550, here are decompositions:

  • 19 + 2147374531 = 2147374550
  • 31 + 2147374519 = 2147374550
  • 73 + 2147374477 = 2147374550
  • 271 + 2147374279 = 2147374550
  • 367 + 2147374183 = 2147374550
  • 463 + 2147374087 = 2147374550
  • 499 + 2147374051 = 2147374550
  • 571 + 2147373979 = 2147374550

Showing the first eight; more decompositions exist.
