Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492672, here are decompositions:

19 + 2147492653 = 2147492672
139 + 2147492533 = 2147492672
151 + 2147492521 = 2147492672
181 + 2147492491 = 2147492672
373 + 2147492299 = 2147492672
433 + 2147492239 = 2147492672
643 + 2147492029 = 2147492672
769 + 2147491903 = 2147492672

Showing the first eight; more decompositions exist.
