Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488900, here are decompositions:

41 + 2147488859 = 2147488900
107 + 2147488793 = 2147488900
149 + 2147488751 = 2147488900
173 + 2147488727 = 2147488900
257 + 2147488643 = 2147488900
281 + 2147488619 = 2147488900
383 + 2147488517 = 2147488900
593 + 2147488307 = 2147488900

Showing the first eight; more decompositions exist.
