Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489840, here are decompositions:

19 + 2147489821 = 2147489840
43 + 2147489797 = 2147489840
127 + 2147489713 = 2147489840
337 + 2147489503 = 2147489840
367 + 2147489473 = 2147489840
439 + 2147489401 = 2147489840
541 + 2147489299 = 2147489840
577 + 2147489263 = 2147489840

Showing the first eight; more decompositions exist.
