Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489428, here are decompositions:

5 + 2147489423 = 2147489428
131 + 2147489297 = 2147489428
137 + 2147489291 = 2147489428
431 + 2147488997 = 2147489428
509 + 2147488919 = 2147489428
521 + 2147488907 = 2147489428
569 + 2147488859 = 2147489428
677 + 2147488751 = 2147489428

Showing the first eight; more decompositions exist.
