Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978942, here are decompositions:

  • 131 + 4294978811 = 4294978942
  • 263 + 4294978679 = 4294978942
  • 281 + 4294978661 = 4294978942
  • 383 + 4294978559 = 4294978942
  • 389 + 4294978553 = 4294978942
  • 431 + 4294978511 = 4294978942
  • 659 + 4294978283 = 4294978942
  • 719 + 4294978223 = 4294978942

Showing the first eight; more decompositions exist.
