Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978170, here are decompositions:

  • 13 + 4294978157 = 4294978170
  • 23 + 4294978147 = 4294978170
  • 37 + 4294978133 = 4294978170
  • 47 + 4294978123 = 4294978170
  • 79 + 4294978091 = 4294978170
  • 83 + 4294978087 = 4294978170
  • 89 + 4294978081 = 4294978170
  • 103 + 4294978067 = 4294978170

Showing the first eight; more decompositions exist.
