Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642852, here are decompositions:

3 + 8642849 = 8642852
13 + 8642839 = 8642852
79 + 8642773 = 8642852
271 + 8642581 = 8642852
523 + 8642329 = 8642852
571 + 8642281 = 8642852
733 + 8642119 = 8642852
1033 + 8641819 = 8642852

Showing the first eight; more decompositions exist.
