Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491826, here are decompositions:

127 + 2147491699 = 2147491826
223 + 2147491603 = 2147491826
229 + 2147491597 = 2147491826
283 + 2147491543 = 2147491826
349 + 2147491477 = 2147491826
409 + 2147491417 = 2147491826
457 + 2147491369 = 2147491826
577 + 2147491249 = 2147491826

Showing the first eight; more decompositions exist.
