Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488356, here are decompositions:

23 + 2147488333 = 2147488356
107 + 2147488249 = 2147488356
109 + 2147488247 = 2147488356
193 + 2147488163 = 2147488356
313 + 2147488043 = 2147488356
347 + 2147488009 = 2147488356
449 + 2147487907 = 2147488356
457 + 2147487899 = 2147488356

Showing the first eight; more decompositions exist.
