Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426516, here are decompositions:

  • 19 + 2147426497 = 2147426516
  • 97 + 2147426419 = 2147426516
  • 139 + 2147426377 = 2147426516
  • 163 + 2147426353 = 2147426516
  • 199 + 2147426317 = 2147426516
  • 349 + 2147426167 = 2147426516
  • 373 + 2147426143 = 2147426516
  • 379 + 2147426137 = 2147426516

Showing the first eight; more decompositions exist.
