Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492888, here are decompositions:

337 + 2147492551 = 2147492888
349 + 2147492539 = 2147492888
367 + 2147492521 = 2147492888
397 + 2147492491 = 2147492888
571 + 2147492317 = 2147492888
727 + 2147492161 = 2147492888
859 + 2147492029 = 2147492888
991 + 2147491897 = 2147492888

Showing the first eight; more decompositions exist.
