Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483666, here are decompositions:

7 + 2147483659 = 2147483666
19 + 2147483647 = 2147483666
37 + 2147483629 = 2147483666
79 + 2147483587 = 2147483666
103 + 2147483563 = 2147483666
313 + 2147483353 = 2147483666
397 + 2147483269 = 2147483666
487 + 2147483179 = 2147483666

Showing the first eight; more decompositions exist.
