Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488654, here are decompositions:

11 + 2147488643 = 2147488654
41 + 2147488613 = 2147488654
137 + 2147488517 = 2147488654
347 + 2147488307 = 2147488654
491 + 2147488163 = 2147488654
503 + 2147488151 = 2147488654
587 + 2147488067 = 2147488654
593 + 2147488061 = 2147488654

Showing the first eight; more decompositions exist.
