Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294951918, here are decompositions:

  • 29 + 4294951889 = 4294951918
  • 41 + 4294951877 = 4294951918
  • 107 + 4294951811 = 4294951918
  • 149 + 4294951769 = 4294951918
  • 167 + 4294951751 = 4294951918
  • 347 + 4294951571 = 4294951918
  • 821 + 4294951097 = 4294951918
  • 827 + 4294951091 = 4294951918

Showing the first eight; more decompositions exist.
