Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978818, here are decompositions:

  • 7 + 4294978811 = 4294978818
  • 19 + 4294978799 = 4294978818
  • 37 + 4294978781 = 4294978818
  • 41 + 4294978777 = 4294978818
  • 61 + 4294978757 = 4294978818
  • 89 + 4294978729 = 4294978818
  • 139 + 4294978679 = 4294978818
  • 157 + 4294978661 = 4294978818

Showing the first eight; more decompositions exist.
