Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294988878, here are decompositions:

  • 17 + 4294988861 = 4294988878
  • 29 + 4294988849 = 4294988878
  • 179 + 4294988699 = 4294988878
  • 269 + 4294988609 = 4294988878
  • 317 + 4294988561 = 4294988878
  • 359 + 4294988519 = 4294988878
  • 449 + 4294988429 = 4294988878
  • 461 + 4294988417 = 4294988878

Showing the first eight; more decompositions exist.
