Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489906, here are decompositions:

7 + 2147489899 = 2147489906
109 + 2147489797 = 2147489906
193 + 2147489713 = 2147489906
433 + 2147489473 = 2147489906
607 + 2147489299 = 2147489906
643 + 2147489263 = 2147489906
823 + 2147489083 = 2147489906
829 + 2147489077 = 2147489906

Showing the first eight; more decompositions exist.
