Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487664, here are decompositions:

41 + 2147487623 = 2147487664
53 + 2147487611 = 2147487664
191 + 2147487473 = 2147487664
263 + 2147487401 = 2147487664
461 + 2147487203 = 2147487664
587 + 2147487077 = 2147487664
683 + 2147486981 = 2147487664
821 + 2147486843 = 2147487664

Showing the first eight; more decompositions exist.
