Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426806, here are decompositions:

  • 59 + 2147426747 = 2147426806
  • 113 + 2147426693 = 2147426806
  • 137 + 2147426669 = 2147426806
  • 149 + 2147426657 = 2147426806
  • 233 + 2147426573 = 2147426806
  • 263 + 2147426543 = 2147426806
  • 347 + 2147426459 = 2147426806
  • 467 + 2147426339 = 2147426806

Showing the first eight; more decompositions exist.
