Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488908, here are decompositions:

41 + 2147488867 = 2147488908
157 + 2147488751 = 2147488908
167 + 2147488741 = 2147488908
181 + 2147488727 = 2147488908
349 + 2147488559 = 2147488908
479 + 2147488429 = 2147488908
491 + 2147488417 = 2147488908
601 + 2147488307 = 2147488908

Showing the first eight; more decompositions exist.
