Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642326, here are decompositions:

23 + 8642303 = 8642326
89 + 8642237 = 8642326
137 + 8642189 = 8642326
167 + 8642159 = 8642326
179 + 8642147 = 8642326
227 + 8642099 = 8642326
263 + 8642063 = 8642326
269 + 8642057 = 8642326

Showing the first eight; more decompositions exist.
