Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642306, here are decompositions:

3 + 8642303 = 8642306
109 + 8642197 = 8642306
199 + 8642107 = 8642306
229 + 8642077 = 8642306
349 + 8641957 = 8642306
397 + 8641909 = 8642306
433 + 8641873 = 8642306
487 + 8641819 = 8642306

Showing the first eight; more decompositions exist.
