Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635386, here are decompositions:

5 + 8635381 = 8635386
73 + 8635313 = 8635386
103 + 8635283 = 8635386
107 + 8635279 = 8635386
113 + 8635273 = 8635386
127 + 8635259 = 8635386
167 + 8635219 = 8635386
223 + 8635163 = 8635386

Showing the first eight; more decompositions exist.
