Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497628, here are decompositions:

139 + 2147497489 = 2147497628
181 + 2147497447 = 2147497628
307 + 2147497321 = 2147497628
487 + 2147497141 = 2147497628
547 + 2147497081 = 2147497628
631 + 2147496997 = 2147497628
691 + 2147496937 = 2147497628
769 + 2147496859 = 2147497628

Showing the first eight; more decompositions exist.
