Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147377976, here are decompositions:

  • 97 + 2147377879 = 2147377976
  • 223 + 2147377753 = 2147377976
  • 277 + 2147377699 = 2147377976
  • 409 + 2147377567 = 2147377976
  • 487 + 2147377489 = 2147377976
  • 547 + 2147377429 = 2147377976
  • 787 + 2147377189 = 2147377976
  • 823 + 2147377153 = 2147377976

Showing the first eight; more decompositions exist.
