Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483840, here are decompositions:

97 + 2147483743 = 2147483840
127 + 2147483713 = 2147483840
181 + 2147483659 = 2147483840
193 + 2147483647 = 2147483840
211 + 2147483629 = 2147483840
277 + 2147483563 = 2147483840
487 + 2147483353 = 2147483840
571 + 2147483269 = 2147483840

Showing the first eight; more decompositions exist.
