Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294994640, here are decompositions:

  • 23 + 4294994617 = 4294994640
  • 149 + 4294994491 = 4294994640
  • 151 + 4294994489 = 4294994640
  • 163 + 4294994477 = 4294994640
  • 191 + 4294994449 = 4294994640
  • 241 + 4294994399 = 4294994640
  • 263 + 4294994377 = 4294994640
  • 269 + 4294994371 = 4294994640

Showing the first eight; more decompositions exist.
