Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147427622, here are decompositions:

  • 29 + 2147427593 = 2147427622
  • 59 + 2147427563 = 2147427622
  • 71 + 2147427551 = 2147427622
  • 149 + 2147427473 = 2147427622
  • 401 + 2147427221 = 2147427622
  • 449 + 2147427173 = 2147427622
  • 929 + 2147426693 = 2147427622
  • 941 + 2147426681 = 2147427622

Showing the first eight; more decompositions exist.
