Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756672, here are decompositions:

3 + 8756669 = 8756672
13 + 8756659 = 8756672
19 + 8756653 = 8756672
79 + 8756593 = 8756672
139 + 8756533 = 8756672
163 + 8756509 = 8756672
271 + 8756401 = 8756672
349 + 8756323 = 8756672

Showing the first eight; more decompositions exist.
