Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978378, here are decompositions:

  • 17 + 4294978361 = 4294978378
  • 71 + 4294978307 = 4294978378
  • 167 + 4294978211 = 4294978378
  • 311 + 4294978067 = 4294978378
  • 389 + 4294977989 = 4294978378
  • 479 + 4294977899 = 4294978378
  • 617 + 4294977761 = 4294978378
  • 947 + 4294977431 = 4294978378

Showing the first eight; more decompositions exist.
