Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472764, here are decompositions:

7 + 2147472757 = 2147472764
13 + 2147472751 = 2147472764
67 + 2147472697 = 2147472764
163 + 2147472601 = 2147472764
421 + 2147472343 = 2147472764
631 + 2147472133 = 2147472764
673 + 2147472091 = 2147472764
727 + 2147472037 = 2147472764

Showing the first eight; more decompositions exist.
