Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487790, here are decompositions:

  • 11 + 2147487779 = 2147487790
  • 17 + 2147487773 = 2147487790
  • 89 + 2147487701 = 2147487790
  • 101 + 2147487689 = 2147487790
  • 167 + 2147487623 = 2147487790
  • 179 + 2147487611 = 2147487790
  • 191 + 2147487599 = 2147487790
  • 281 + 2147487509 = 2147487790

Showing the first eight; more decompositions exist.
