Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294951978, here are decompositions:

  • 11 + 4294951967 = 4294951978
  • 29 + 4294951949 = 4294951978
  • 47 + 4294951931 = 4294951978
  • 89 + 4294951889 = 4294951978
  • 101 + 4294951877 = 4294951978
  • 167 + 4294951811 = 4294951978
  • 227 + 4294951751 = 4294951978
  • 269 + 4294951709 = 4294951978

Showing the first eight; more decompositions exist.
