Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489886, here are decompositions:

13 + 2147489873 = 2147489886
37 + 2147489849 = 2147489886
43 + 2147489843 = 2147489886
67 + 2147489819 = 2147489886
89 + 2147489797 = 2147489886
173 + 2147489713 = 2147489886
233 + 2147489653 = 2147489886
307 + 2147489579 = 2147489886

Showing the first eight; more decompositions exist.
