Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492558, here are decompositions:

7 + 2147492551 = 2147492558
19 + 2147492539 = 2147492558
31 + 2147492527 = 2147492558
37 + 2147492521 = 2147492558
67 + 2147492491 = 2147492558
229 + 2147492329 = 2147492558
241 + 2147492317 = 2147492558
397 + 2147492161 = 2147492558

Showing the first eight; more decompositions exist.
