Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621084, here are decompositions:

7 + 8621077 = 8621084
37 + 8621047 = 8621084
67 + 8621017 = 8621084
211 + 8620873 = 8621084
223 + 8620861 = 8621084
337 + 8620747 = 8621084
397 + 8620687 = 8621084
421 + 8620663 = 8621084

Showing the first eight; more decompositions exist.
