Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609238, here are decompositions:

31 + 8609207 = 8609238
89 + 8609149 = 8609238
101 + 8609137 = 8609238
109 + 8609129 = 8609238
139 + 8609099 = 8609238
151 + 8609087 = 8609238
307 + 8608931 = 8609238
331 + 8608907 = 8609238

Showing the first eight; more decompositions exist.
