Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669238, here are decompositions:

5 + 8669233 = 8669238
31 + 8669207 = 8669238
59 + 8669179 = 8669238
79 + 8669159 = 8669238
131 + 8669107 = 8669238
167 + 8669071 = 8669238
197 + 8669041 = 8669238
211 + 8669027 = 8669238

Showing the first eight; more decompositions exist.
