Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642052, here are decompositions:

19 + 8642033 = 8642052
61 + 8641991 = 8642052
103 + 8641949 = 8642052
179 + 8641873 = 8642052
233 + 8641819 = 8642052
269 + 8641783 = 8642052
271 + 8641781 = 8642052
311 + 8641741 = 8642052

Showing the first eight; more decompositions exist.
