Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147477740, here are decompositions:

  • 3 + 2147477737 = 2147477740
  • 41 + 2147477699 = 2147477740
  • 53 + 2147477687 = 2147477740
  • 59 + 2147477681 = 2147477740
  • 113 + 2147477627 = 2147477740
  • 227 + 2147477513 = 2147477740
  • 347 + 2147477393 = 2147477740
  • 467 + 2147477273 = 2147477740

Showing the first eight; more decompositions exist.
