Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487500, here are decompositions:

97 + 2147487403 = 2147487500
127 + 2147487373 = 2147487500
157 + 2147487343 = 2147487500
199 + 2147487301 = 2147487500
241 + 2147487259 = 2147487500
313 + 2147487187 = 2147487500
331 + 2147487169 = 2147487500
643 + 2147486857 = 2147487500

Showing the first eight; more decompositions exist.
