Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487858, here are decompositions:

  • 29 + 2147487829 = 2147487858
  • 31 + 2147487827 = 2147487858
  • 41 + 2147487817 = 2147487858
  • 59 + 2147487799 = 2147487858
  • 79 + 2147487779 = 2147487858
  • 101 + 2147487757 = 2147487858
  • 107 + 2147487751 = 2147487858
  • 157 + 2147487701 = 2147487858

Showing the first eight; more decompositions exist.
