Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627872, here are decompositions:

5 + 8627867 = 8627872
59 + 8627813 = 8627872
131 + 8627741 = 8627872
173 + 8627699 = 8627872
179 + 8627693 = 8627872
191 + 8627681 = 8627872
233 + 8627639 = 8627872
263 + 8627609 = 8627872

Showing the first eight; more decompositions exist.
