Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492538, here are decompositions:

5 + 2147492533 = 2147492538
11 + 2147492527 = 2147492538
17 + 2147492521 = 2147492538
47 + 2147492491 = 2147492538
109 + 2147492429 = 2147492538
151 + 2147492387 = 2147492538
167 + 2147492371 = 2147492538
199 + 2147492339 = 2147492538

Showing the first eight; more decompositions exist.
