Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483686, here are decompositions:

107 + 2147483579 = 2147483686
137 + 2147483549 = 2147483686
197 + 2147483489 = 2147483686
263 + 2147483423 = 2147483686
449 + 2147483237 = 2147483686
563 + 2147483123 = 2147483686
617 + 2147483069 = 2147483686
653 + 2147483033 = 2147483686

Showing the first eight; more decompositions exist.
