Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8652140, here are decompositions:

43 + 8652097 = 8652140
61 + 8652079 = 8652140
103 + 8652037 = 8652140
127 + 8652013 = 8652140
163 + 8651977 = 8652140
181 + 8651959 = 8652140
199 + 8651941 = 8652140
223 + 8651917 = 8652140

Showing the first eight; more decompositions exist.
