Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469666, here are decompositions:

  • 7 + 2147469659 = 2147469666
  • 29 + 2147469637 = 2147469666
  • 37 + 2147469629 = 2147469666
  • 47 + 2147469619 = 2147469666
  • 73 + 2147469593 = 2147469666
  • 113 + 2147469553 = 2147469666
  • 337 + 2147469329 = 2147469666
  • 383 + 2147469283 = 2147469666

Showing the first eight; more decompositions exist.
