Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492720, here are decompositions:

19 + 2147492701 = 2147492720
67 + 2147492653 = 2147492720
181 + 2147492539 = 2147492720
193 + 2147492527 = 2147492720
199 + 2147492521 = 2147492720
229 + 2147492491 = 2147492720
349 + 2147492371 = 2147492720
367 + 2147492353 = 2147492720

Showing the first eight; more decompositions exist.
