Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978398, here are decompositions:

  • 17 + 4294978381 = 4294978398
  • 37 + 4294978361 = 4294978398
  • 71 + 4294978327 = 4294978398
  • 89 + 4294978309 = 4294978398
  • 149 + 4294978249 = 4294978398
  • 167 + 4294978231 = 4294978398
  • 197 + 4294978201 = 4294978398
  • 229 + 4294978169 = 4294978398

Showing the first eight; more decompositions exist.
