Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498398, here are decompositions:

5 + 2147498393 = 2147498398
11 + 2147498387 = 2147498398
251 + 2147498147 = 2147498398
257 + 2147498141 = 2147498398
281 + 2147498117 = 2147498398
449 + 2147497949 = 2147498398
491 + 2147497907 = 2147498398
509 + 2147497889 = 2147498398

Showing the first eight; more decompositions exist.
