Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294990986, here are decompositions:

  • 19 + 4294990967 = 4294990986
  • 73 + 4294990913 = 4294990986
  • 199 + 4294990787 = 4294990986
  • 257 + 4294990729 = 4294990986
  • 263 + 4294990723 = 4294990986
  • 347 + 4294990639 = 4294990986
  • 389 + 4294990597 = 4294990986
  • 409 + 4294990577 = 4294990986

Showing the first eight; more decompositions exist.
