Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978180, here are decompositions:

  • 11 + 4294978169 = 4294978180
  • 23 + 4294978157 = 4294978180
  • 47 + 4294978133 = 4294978180
  • 89 + 4294978091 = 4294978180
  • 113 + 4294978067 = 4294978180
  • 191 + 4294977989 = 4294978180
  • 281 + 4294977899 = 4294978180
  • 419 + 4294977761 = 4294978180

Showing the first eight; more decompositions exist.
