Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978138, here are decompositions:

  • 5 + 4294978133 = 4294978138
  • 47 + 4294978091 = 4294978138
  • 71 + 4294978067 = 4294978138
  • 149 + 4294977989 = 4294978138
  • 239 + 4294977899 = 4294978138
  • 257 + 4294977881 = 4294978138
  • 467 + 4294977671 = 4294978138
  • 719 + 4294977419 = 4294978138

Showing the first eight; more decompositions exist.
