Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294977640, here are decompositions:

  • 17 + 4294977623 = 4294977640
  • 137 + 4294977503 = 4294977640
  • 227 + 4294977413 = 4294977640
  • 251 + 4294977389 = 4294977640
  • 293 + 4294977347 = 4294977640
  • 311 + 4294977329 = 4294977640
  • 353 + 4294977287 = 4294977640
  • 467 + 4294977173 = 4294977640

Showing the first eight; more decompositions exist.
