Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147565806, here are decompositions:

  • 13 + 2147565793 = 2147565806
  • 97 + 2147565709 = 2147565806
  • 109 + 2147565697 = 2147565806
  • 229 + 2147565577 = 2147565806
  • 277 + 2147565529 = 2147565806
  • 283 + 2147565523 = 2147565806
  • 313 + 2147565493 = 2147565806
  • 409 + 2147565397 = 2147565806

Showing the first eight; more decompositions exist.
