Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978642, here are decompositions:

  • 83 + 4294978559 = 4294978642
  • 89 + 4294978553 = 4294978642
  • 131 + 4294978511 = 4294978642
  • 281 + 4294978361 = 4294978642
  • 359 + 4294978283 = 4294978642
  • 419 + 4294978223 = 4294978642
  • 431 + 4294978211 = 4294978642
  • 509 + 4294978133 = 4294978642

Showing the first eight; more decompositions exist.
