Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978542, here are decompositions:

  • 31 + 4294978511 = 4294978542
  • 53 + 4294978489 = 4294978542
  • 181 + 4294978361 = 4294978542
  • 229 + 4294978313 = 4294978542
  • 233 + 4294978309 = 4294978542
  • 293 + 4294978249 = 4294978542
  • 311 + 4294978231 = 4294978542
  • 331 + 4294978211 = 4294978542

Showing the first eight; more decompositions exist.
