Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699238, here are decompositions:

5 + 8699233 = 8699238
11 + 8699227 = 8699238
19 + 8699219 = 8699238
59 + 8699179 = 8699238
71 + 8699167 = 8699238
199 + 8699039 = 8699238
241 + 8698997 = 8699238
269 + 8698969 = 8699238

Showing the first eight; more decompositions exist.
