Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621300, here are decompositions:

19 + 8621281 = 8621300
157 + 8621143 = 8621300
199 + 8621101 = 8621300
211 + 8621089 = 8621300
223 + 8621077 = 8621300
283 + 8621017 = 8621300
307 + 8620993 = 8621300
349 + 8620951 = 8621300

Showing the first eight; more decompositions exist.
