Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635212, here are decompositions:

13 + 8635199 = 8635212
71 + 8635141 = 8635212
139 + 8635073 = 8635212
151 + 8635061 = 8635212
163 + 8635049 = 8635212
191 + 8635021 = 8635212
241 + 8634971 = 8635212
251 + 8634961 = 8635212

Showing the first eight; more decompositions exist.
