Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488528, here are decompositions:

11 + 2147488517 = 2147488528
281 + 2147488247 = 2147488528
461 + 2147488067 = 2147488528
467 + 2147488061 = 2147488528
587 + 2147487941 = 2147488528
659 + 2147487869 = 2147488528
701 + 2147487827 = 2147488528
827 + 2147487701 = 2147488528

Showing the first eight; more decompositions exist.
