Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618838, here are decompositions:

5 + 8618833 = 8618838
29 + 8618809 = 8618838
79 + 8618759 = 8618838
89 + 8618749 = 8618838
101 + 8618737 = 8618838
139 + 8618699 = 8618838
149 + 8618689 = 8618838
157 + 8618681 = 8618838

Showing the first eight; more decompositions exist.
