Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488198, here are decompositions:

47 + 2147488151 = 2147488198
131 + 2147488067 = 2147488198
137 + 2147488061 = 2147488198
197 + 2147488001 = 2147488198
257 + 2147487941 = 2147488198
419 + 2147487779 = 2147488198
509 + 2147487689 = 2147488198
587 + 2147487611 = 2147488198

Showing the first eight; more decompositions exist.
