Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484920, here are decompositions:

43 + 2147484877 = 2147484920
199 + 2147484721 = 2147484920
223 + 2147484697 = 2147484920
241 + 2147484679 = 2147484920
307 + 2147484613 = 2147484920
367 + 2147484553 = 2147484920
379 + 2147484541 = 2147484920
421 + 2147484499 = 2147484920

Showing the first eight; more decompositions exist.
