Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147558822, here are decompositions:

  • 193 + 2147558629 = 2147558822
  • 229 + 2147558593 = 2147558822
  • 421 + 2147558401 = 2147558822
  • 433 + 2147558389 = 2147558822
  • 439 + 2147558383 = 2147558822
  • 463 + 2147558359 = 2147558822
  • 631 + 2147558191 = 2147558822
  • 769 + 2147558053 = 2147558822

Showing the first eight; more decompositions exist.
