Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487542, here are decompositions:

139 + 2147487403 = 2147487542
199 + 2147487343 = 2147487542
241 + 2147487301 = 2147487542
283 + 2147487259 = 2147487542
373 + 2147487169 = 2147487542
691 + 2147486851 = 2147487542
751 + 2147486791 = 2147487542
853 + 2147486689 = 2147487542

Showing the first eight; more decompositions exist.
