Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467782, here are decompositions:

  • 13 + 2147467769 = 2147467782
  • 23 + 2147467759 = 2147467782
  • 71 + 2147467711 = 2147467782
  • 113 + 2147467669 = 2147467782
  • 151 + 2147467631 = 2147467782
  • 199 + 2147467583 = 2147467782
  • 223 + 2147467559 = 2147467782
  • 311 + 2147467471 = 2147467782

Showing the first eight; more decompositions exist.
