Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627844, here are decompositions:

11 + 8627833 = 8627844
31 + 8627813 = 8627844
37 + 8627807 = 8627844
67 + 8627777 = 8627844
103 + 8627741 = 8627844
131 + 8627713 = 8627844
151 + 8627693 = 8627844
163 + 8627681 = 8627844

Showing the first eight; more decompositions exist.
