Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472788, here are decompositions:

31 + 2147472757 = 2147472788
37 + 2147472751 = 2147472788
367 + 2147472421 = 2147472788
499 + 2147472289 = 2147472788
751 + 2147472037 = 2147472788
907 + 2147471881 = 2147472788
1249 + 2147471539 = 2147472788
1699 + 2147471089 = 2147472788

Showing the first eight; more decompositions exist.
