Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635220, here are decompositions:

79 + 8635141 = 8635220
103 + 8635117 = 8635220
127 + 8635093 = 8635220
163 + 8635057 = 8635220
199 + 8635021 = 8635220
313 + 8634907 = 8635220
331 + 8634889 = 8635220
337 + 8634883 = 8635220

Showing the first eight; more decompositions exist.
