Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147375660, here are decompositions:

  • 19 + 2147375641 = 2147375660
  • 139 + 2147375521 = 2147375660
  • 151 + 2147375509 = 2147375660
  • 223 + 2147375437 = 2147375660
  • 271 + 2147375389 = 2147375660
  • 487 + 2147375173 = 2147375660
  • 499 + 2147375161 = 2147375660
  • 523 + 2147375137 = 2147375660

Showing the first eight; more decompositions exist.
