Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492508, here are decompositions:

17 + 2147492491 = 2147492508
19 + 2147492489 = 2147492508
61 + 2147492447 = 2147492508
79 + 2147492429 = 2147492508
137 + 2147492371 = 2147492508
179 + 2147492329 = 2147492508
181 + 2147492327 = 2147492508
191 + 2147492317 = 2147492508

Showing the first eight; more decompositions exist.
