Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294969878, here are decompositions:

  • 7 + 4294969871 = 4294969878
  • 47 + 4294969831 = 4294969878
  • 71 + 4294969807 = 4294969878
  • 97 + 4294969781 = 4294969878
  • 131 + 4294969747 = 4294969878
  • 139 + 4294969739 = 4294969878
  • 149 + 4294969729 = 4294969878
  • 151 + 4294969727 = 4294969878

Showing the first eight; more decompositions exist.
