Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489900, here are decompositions:

79 + 2147489821 = 2147489900
103 + 2147489797 = 2147489900
313 + 2147489587 = 2147489900
397 + 2147489503 = 2147489900
463 + 2147489437 = 2147489900
499 + 2147489401 = 2147489900
601 + 2147489299 = 2147489900
757 + 2147489143 = 2147489900

Showing the first eight; more decompositions exist.
