Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294955728, here are decompositions:

  • 311 + 4294955417 = 4294955728
  • 347 + 4294955381 = 4294955728
  • 419 + 4294955309 = 4294955728
  • 449 + 4294955279 = 4294955728
  • 491 + 4294955237 = 4294955728
  • 587 + 4294955141 = 4294955728
  • 719 + 4294955009 = 4294955728
  • 761 + 4294954967 = 4294955728

Showing the first eight; more decompositions exist.
