Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472728, here are decompositions:

31 + 2147472697 = 2147472728
127 + 2147472601 = 2147472728
229 + 2147472499 = 2147472728
307 + 2147472421 = 2147472728
439 + 2147472289 = 2147472728
619 + 2147472109 = 2147472728
691 + 2147472037 = 2147472728
1021 + 2147471707 = 2147472728

Showing the first eight; more decompositions exist.
