Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978418, here are decompositions:

  • 19 + 4294978399 = 4294978418
  • 37 + 4294978381 = 4294978418
  • 109 + 4294978309 = 4294978418
  • 271 + 4294978147 = 4294978418
  • 331 + 4294978087 = 4294978418
  • 337 + 4294978081 = 4294978418
  • 397 + 4294978021 = 4294978418
  • 457 + 4294977961 = 4294978418

Showing the first eight; more decompositions exist.
