Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635424, here are decompositions:

43 + 8635381 = 8635424
73 + 8635351 = 8635424
103 + 8635321 = 8635424
151 + 8635273 = 8635424
163 + 8635261 = 8635424
283 + 8635141 = 8635424
307 + 8635117 = 8635424
331 + 8635093 = 8635424

Showing the first eight; more decompositions exist.
