Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472276, here are decompositions:

13 + 2147472263 = 2147472276
17 + 2147472259 = 2147472276
139 + 2147472137 = 2147472276
167 + 2147472109 = 2147472276
223 + 2147472053 = 2147472276
233 + 2147472043 = 2147472276
239 + 2147472037 = 2147472276
283 + 2147471993 = 2147472276

Showing the first eight; more decompositions exist.
