Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635970, here are decompositions:

3 + 8635967 = 8635970
19 + 8635951 = 8635970
37 + 8635933 = 8635970
43 + 8635927 = 8635970
73 + 8635897 = 8635970
103 + 8635867 = 8635970
193 + 8635777 = 8635970
241 + 8635729 = 8635970

Showing the first eight; more decompositions exist.
