Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497988, here are decompositions:

67 + 2147497921 = 2147497988
271 + 2147497717 = 2147497988
499 + 2147497489 = 2147497988
541 + 2147497447 = 2147497988
577 + 2147497411 = 2147497988
751 + 2147497237 = 2147497988
787 + 2147497201 = 2147497988
907 + 2147497081 = 2147497988

Showing the first eight; more decompositions exist.
