Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978420, here are decompositions:

  • 59 + 4294978361 = 4294978420
  • 107 + 4294978313 = 4294978420
  • 113 + 4294978307 = 4294978420
  • 137 + 4294978283 = 4294978420
  • 197 + 4294978223 = 4294978420
  • 251 + 4294978169 = 4294978420
  • 263 + 4294978157 = 4294978420
  • 353 + 4294978067 = 4294978420

Showing the first eight; more decompositions exist.
