Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492930, here are decompositions:

7 + 2147492923 = 2147492930
229 + 2147492701 = 2147492930
277 + 2147492653 = 2147492930
379 + 2147492551 = 2147492930
397 + 2147492533 = 2147492930
409 + 2147492521 = 2147492930
439 + 2147492491 = 2147492930
577 + 2147492353 = 2147492930

Showing the first eight; more decompositions exist.
