Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635242, here are decompositions:

23 + 8635219 = 8635242
43 + 8635199 = 8635242
79 + 8635163 = 8635242
101 + 8635141 = 8635242
149 + 8635093 = 8635242
181 + 8635061 = 8635242
193 + 8635049 = 8635242
199 + 8635043 = 8635242

Showing the first eight; more decompositions exist.
