Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294974640, here are decompositions:

  • 41 + 4294974599 = 4294974640
  • 59 + 4294974581 = 4294974640
  • 71 + 4294974569 = 4294974640
  • 113 + 4294974527 = 4294974640
  • 227 + 4294974413 = 4294974640
  • 317 + 4294974323 = 4294974640
  • 353 + 4294974287 = 4294974640
  • 401 + 4294974239 = 4294974640

Showing the first eight; more decompositions exist.
