Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467812, here are decompositions:

  • 11 + 2147467801 = 2147467812
  • 19 + 2147467793 = 2147467812
  • 43 + 2147467769 = 2147467812
  • 53 + 2147467759 = 2147467812
  • 79 + 2147467733 = 2147467812
  • 101 + 2147467711 = 2147467812
  • 173 + 2147467639 = 2147467812
  • 181 + 2147467631 = 2147467812

Showing the first eight; more decompositions exist.
