Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987656, here are decompositions:

  • 5 + 4294987651 = 4294987656
  • 67 + 4294987589 = 4294987656
  • 229 + 4294987427 = 4294987656
  • 263 + 4294987393 = 4294987656
  • 269 + 4294987387 = 4294987656
  • 353 + 4294987303 = 4294987656
  • 367 + 4294987289 = 4294987656
  • 499 + 4294987157 = 4294987656

Showing the first eight; more decompositions exist.
