Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642300, here are decompositions:

19 + 8642281 = 8642300
103 + 8642197 = 8642300
127 + 8642173 = 8642300
181 + 8642119 = 8642300
193 + 8642107 = 8642300
223 + 8642077 = 8642300
241 + 8642059 = 8642300
313 + 8641987 = 8642300

Showing the first eight; more decompositions exist.
