Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488620, here are decompositions:

  • 7 + 2147488613 = 2147488620
  • 41 + 2147488579 = 2147488620
  • 47 + 2147488573 = 2147488620
  • 61 + 2147488559 = 2147488620
  • 103 + 2147488517 = 2147488620
  • 191 + 2147488429 = 2147488620
  • 239 + 2147488381 = 2147488620
  • 313 + 2147488307 = 2147488620

Showing the first eight; more decompositions exist.
