Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488738, here are decompositions:

11 + 2147488727 = 2147488738
47 + 2147488691 = 2147488738
179 + 2147488559 = 2147488738
431 + 2147488307 = 2147488738
491 + 2147488247 = 2147488738
587 + 2147488151 = 2147488738
677 + 2147488061 = 2147488738
797 + 2147487941 = 2147488738

Showing the first eight; more decompositions exist.
