Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147521066, here are decompositions:

  • 83 + 2147520983 = 2147521066
  • 113 + 2147520953 = 2147521066
  • 227 + 2147520839 = 2147521066
  • 239 + 2147520827 = 2147521066
  • 263 + 2147520803 = 2147521066
  • 269 + 2147520797 = 2147521066
  • 293 + 2147520773 = 2147521066
  • 347 + 2147520719 = 2147521066

Showing the first eight; more decompositions exist.
