Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489578, here are decompositions:

41 + 2147489537 = 2147489578
137 + 2147489441 = 2147489578
281 + 2147489297 = 2147489578
491 + 2147489087 = 2147489578
659 + 2147488919 = 2147489578
719 + 2147488859 = 2147489578
827 + 2147488751 = 2147489578
887 + 2147488691 = 2147489578

Showing the first eight; more decompositions exist.
