Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491498, here are decompositions:

137 + 2147491361 = 2147491498
149 + 2147491349 = 2147491498
179 + 2147491319 = 2147491498
281 + 2147491217 = 2147491498
359 + 2147491139 = 2147491498
431 + 2147491067 = 2147491498
461 + 2147491037 = 2147491498
479 + 2147491019 = 2147491498

Showing the first eight; more decompositions exist.
