Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426980, here are decompositions:

  • 29 + 2147426951 = 2147426980
  • 137 + 2147426843 = 2147426980
  • 233 + 2147426747 = 2147426980
  • 311 + 2147426669 = 2147426980
  • 509 + 2147426471 = 2147426980
  • 521 + 2147426459 = 2147426980
  • 641 + 2147426339 = 2147426980
  • 773 + 2147426207 = 2147426980

Showing the first eight; more decompositions exist.
