Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978878, here are decompositions:

  • 5 + 4294978873 = 4294978878
  • 11 + 4294978867 = 4294978878
  • 67 + 4294978811 = 4294978878
  • 79 + 4294978799 = 4294978878
  • 97 + 4294978781 = 4294978878
  • 101 + 4294978777 = 4294978878
  • 149 + 4294978729 = 4294978878
  • 199 + 4294978679 = 4294978878

Showing the first eight; more decompositions exist.
