Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147591306, here are decompositions:

  • 13 + 2147591293 = 2147591306
  • 19 + 2147591287 = 2147591306
  • 43 + 2147591263 = 2147591306
  • 73 + 2147591233 = 2147591306
  • 199 + 2147591107 = 2147591306
  • 229 + 2147591077 = 2147591306
  • 373 + 2147590933 = 2147591306
  • 379 + 2147590927 = 2147591306

Showing the first eight; more decompositions exist.
