Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612238, here are decompositions:

17 + 8612221 = 8612238
29 + 8612209 = 8612238
71 + 8612167 = 8612238
139 + 8612099 = 8612238
149 + 8612089 = 8612238
179 + 8612059 = 8612238
181 + 8612057 = 8612238
199 + 8612039 = 8612238

Showing the first eight; more decompositions exist.
