Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426556, here are decompositions:

  • 5 + 2147426551 = 2147426556
  • 13 + 2147426543 = 2147426556
  • 29 + 2147426527 = 2147426556
  • 59 + 2147426497 = 2147426556
  • 89 + 2147426467 = 2147426556
  • 97 + 2147426459 = 2147426556
  • 137 + 2147426419 = 2147426556
  • 157 + 2147426399 = 2147426556

Showing the first eight; more decompositions exist.
