Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487984, here are decompositions:

43 + 2147487941 = 2147487984
53 + 2147487931 = 2147487984
113 + 2147487871 = 2147487984
151 + 2147487833 = 2147487984
157 + 2147487827 = 2147487984
167 + 2147487817 = 2147487984
181 + 2147487803 = 2147487984
211 + 2147487773 = 2147487984

Showing the first eight; more decompositions exist.
