Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978218, here are decompositions:

  • 7 + 4294978211 = 4294978218
  • 17 + 4294978201 = 4294978218
  • 61 + 4294978157 = 4294978218
  • 71 + 4294978147 = 4294978218
  • 127 + 4294978091 = 4294978218
  • 131 + 4294978087 = 4294978218
  • 137 + 4294978081 = 4294978218
  • 151 + 4294978067 = 4294978218

Showing the first eight; more decompositions exist.
