Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491790, here are decompositions:

181 + 2147491609 = 2147491790
193 + 2147491597 = 2147491790
313 + 2147491477 = 2147491790
373 + 2147491417 = 2147491790
421 + 2147491369 = 2147491790
541 + 2147491249 = 2147491790
571 + 2147491219 = 2147491790
709 + 2147491081 = 2147491790

Showing the first eight; more decompositions exist.
