Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489108, here are decompositions:

19 + 2147489089 = 2147489108
31 + 2147489077 = 2147489108
241 + 2147488867 = 2147489108
367 + 2147488741 = 2147489108
691 + 2147488417 = 2147489108
727 + 2147488381 = 2147489108
829 + 2147488279 = 2147489108
859 + 2147488249 = 2147489108

Showing the first eight; more decompositions exist.
