Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660238, here are decompositions:

5 + 8660233 = 8660238
11 + 8660227 = 8660238
17 + 8660221 = 8660238
61 + 8660177 = 8660238
131 + 8660107 = 8660238
151 + 8660087 = 8660238
157 + 8660081 = 8660238
199 + 8660039 = 8660238

Showing the first eight; more decompositions exist.
