Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8602820, here are decompositions:

3 + 8602817 = 8602820
13 + 8602807 = 8602820
43 + 8602777 = 8602820
67 + 8602753 = 8602820
271 + 8602549 = 8602820
277 + 8602543 = 8602820
313 + 8602507 = 8602820
349 + 8602471 = 8602820

Showing the first eight; more decompositions exist.
