Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489198, here are decompositions:

109 + 2147489089 = 2147489198
139 + 2147489059 = 2147489198
181 + 2147489017 = 2147489198
331 + 2147488867 = 2147489198
457 + 2147488741 = 2147489198
619 + 2147488579 = 2147489198
769 + 2147488429 = 2147489198
787 + 2147488411 = 2147489198

Showing the first eight; more decompositions exist.
