Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660838, here are decompositions:

19 + 8660819 = 8660838
41 + 8660797 = 8660838
71 + 8660767 = 8660838
97 + 8660741 = 8660838
139 + 8660699 = 8660838
149 + 8660689 = 8660838
157 + 8660681 = 8660838
167 + 8660671 = 8660838

Showing the first eight; more decompositions exist.
