Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487620, here are decompositions:

13 + 2147487607 = 2147487620
79 + 2147487541 = 2147487620
211 + 2147487409 = 2147487620
277 + 2147487343 = 2147487620
373 + 2147487247 = 2147487620
433 + 2147487187 = 2147487620
463 + 2147487157 = 2147487620
571 + 2147487049 = 2147487620

Showing the first eight; more decompositions exist.
