Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487198, here are decompositions:

11 + 2147487187 = 2147487198
29 + 2147487169 = 2147487198
41 + 2147487157 = 2147487198
139 + 2147487059 = 2147487198
149 + 2147487049 = 2147487198
229 + 2147486969 = 2147487198
271 + 2147486927 = 2147487198
347 + 2147486851 = 2147487198

Showing the first eight; more decompositions exist.
