Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497828, here are decompositions:

59 + 2147497769 = 2147497828
71 + 2147497757 = 2147497828
131 + 2147497697 = 2147497828
137 + 2147497691 = 2147497828
167 + 2147497661 = 2147497828
257 + 2147497571 = 2147497828
269 + 2147497559 = 2147497828
347 + 2147497481 = 2147497828

Showing the first eight; more decompositions exist.
