Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472836, here are decompositions:

79 + 2147472757 = 2147472836
139 + 2147472697 = 2147472836
337 + 2147472499 = 2147472836
367 + 2147472469 = 2147472836
463 + 2147472373 = 2147472836
547 + 2147472289 = 2147472836
577 + 2147472259 = 2147472836
727 + 2147472109 = 2147472836

Showing the first eight; more decompositions exist.
