Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489488, here are decompositions:

5 + 2147489483 = 2147489488
47 + 2147489441 = 2147489488
191 + 2147489297 = 2147489488
197 + 2147489291 = 2147489488
281 + 2147489207 = 2147489488
401 + 2147489087 = 2147489488
491 + 2147488997 = 2147489488
569 + 2147488919 = 2147489488

Showing the first eight; more decompositions exist.
