Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473148, here are decompositions:

31 + 2147473117 = 2147473148
397 + 2147472751 = 2147473148
547 + 2147472601 = 2147473148
727 + 2147472421 = 2147473148
859 + 2147472289 = 2147473148
1039 + 2147472109 = 2147473148
1567 + 2147471581 = 2147473148
1609 + 2147471539 = 2147473148

Showing the first eight; more decompositions exist.
