Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662820, here are decompositions:

13 + 8662807 = 8662820
37 + 8662783 = 8662820
73 + 8662747 = 8662820
163 + 8662657 = 8662820
223 + 8662597 = 8662820
241 + 8662579 = 8662820
337 + 8662483 = 8662820
349 + 8662471 = 8662820

Showing the first eight; more decompositions exist.
