Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978140, here are decompositions:

  • 7 + 4294978133 = 4294978140
  • 17 + 4294978123 = 4294978140
  • 53 + 4294978087 = 4294978140
  • 59 + 4294978081 = 4294978140
  • 73 + 4294978067 = 4294978140
  • 83 + 4294978057 = 4294978140
  • 107 + 4294978033 = 4294978140
  • 113 + 4294978027 = 4294978140

Showing the first eight; more decompositions exist.
