Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987440, here are decompositions:

  • 13 + 4294987427 = 4294987440
  • 47 + 4294987393 = 4294987440
  • 53 + 4294987387 = 4294987440
  • 83 + 4294987357 = 4294987440
  • 109 + 4294987331 = 4294987440
  • 137 + 4294987303 = 4294987440
  • 151 + 4294987289 = 4294987440
  • 283 + 4294987157 = 4294987440

Showing the first eight; more decompositions exist.
