Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635442, here are decompositions:

19 + 8635423 = 8635442
61 + 8635381 = 8635442
163 + 8635279 = 8635442
181 + 8635261 = 8635442
223 + 8635219 = 8635442
349 + 8635093 = 8635442
421 + 8635021 = 8635442
601 + 8634841 = 8635442

Showing the first eight; more decompositions exist.
