Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489720, here are decompositions:

3 + 2147489717 = 2147489720
7 + 2147489713 = 2147489720
67 + 2147489653 = 2147489720
283 + 2147489437 = 2147489720
373 + 2147489347 = 2147489720
421 + 2147489299 = 2147489720
457 + 2147489263 = 2147489720
577 + 2147489143 = 2147489720

Showing the first eight; more decompositions exist.
