Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492994, here are decompositions:

71 + 2147492923 = 2147492994
151 + 2147492843 = 2147492994
293 + 2147492701 = 2147492994
373 + 2147492621 = 2147492994
397 + 2147492597 = 2147492994
443 + 2147492551 = 2147492994
461 + 2147492533 = 2147492994
467 + 2147492527 = 2147492994

Showing the first eight; more decompositions exist.
