Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489888, here are decompositions:

67 + 2147489821 = 2147489888
487 + 2147489401 = 2147489888
541 + 2147489347 = 2147489888
811 + 2147489077 = 2147489888
829 + 2147489059 = 2147489888
1021 + 2147488867 = 2147489888
1459 + 2147488429 = 2147489888
1471 + 2147488417 = 2147489888

Showing the first eight; more decompositions exist.
