Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627838, here are decompositions:

5 + 8627833 = 8627838
29 + 8627809 = 8627838
31 + 8627807 = 8627838
61 + 8627777 = 8627838
97 + 8627741 = 8627838
137 + 8627701 = 8627838
139 + 8627699 = 8627838
157 + 8627681 = 8627838

Showing the first eight; more decompositions exist.
