Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8675238, here are decompositions:

17 + 8675221 = 8675238
41 + 8675197 = 8675238
101 + 8675137 = 8675238
127 + 8675111 = 8675238
139 + 8675099 = 8675238
179 + 8675059 = 8675238
191 + 8675047 = 8675238
211 + 8675027 = 8675238

Showing the first eight; more decompositions exist.
