Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489178, here are decompositions:

89 + 2147489089 = 2147489178
101 + 2147489077 = 2147489178
181 + 2147488997 = 2147489178
271 + 2147488907 = 2147489178
311 + 2147488867 = 2147489178
487 + 2147488691 = 2147489178
599 + 2147488579 = 2147489178
619 + 2147488559 = 2147489178

Showing the first eight; more decompositions exist.
