Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488240, here are decompositions:

89 + 2147488151 = 2147488240
173 + 2147488067 = 2147488240
179 + 2147488061 = 2147488240
197 + 2147488043 = 2147488240
239 + 2147488001 = 2147488240
461 + 2147487779 = 2147488240
467 + 2147487773 = 2147488240
617 + 2147487623 = 2147488240

Showing the first eight; more decompositions exist.
