Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483648, here are decompositions:

  • 19 + 2147483629 = 2147483648
  • 61 + 2147483587 = 2147483648
  • 151 + 2147483497 = 2147483648
  • 379 + 2147483269 = 2147483648
  • 571 + 2147483077 = 2147483648
  • 619 + 2147483029 = 2147483648
  • 727 + 2147482921 = 2147483648
  • 829 + 2147482819 = 2147483648

Showing the first eight; more decompositions exist.
