Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8683838, here are decompositions:

109 + 8683729 = 8683838
139 + 8683699 = 8683838
151 + 8683687 = 8683838
157 + 8683681 = 8683838
181 + 8683657 = 8683838
199 + 8683639 = 8683838
307 + 8683531 = 8683838
379 + 8683459 = 8683838

Showing the first eight; more decompositions exist.
