Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642346, here are decompositions:

17 + 8642329 = 8642346
43 + 8642303 = 8642346
109 + 8642237 = 8642346
149 + 8642197 = 8642346
157 + 8642189 = 8642346
173 + 8642173 = 8642346
199 + 8642147 = 8642346
227 + 8642119 = 8642346

Showing the first eight; more decompositions exist.
