Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635240, here are decompositions:

41 + 8635199 = 8635240
167 + 8635073 = 8635240
179 + 8635061 = 8635240
191 + 8635049 = 8635240
197 + 8635043 = 8635240
269 + 8634971 = 8635240
293 + 8634947 = 8635240
359 + 8634881 = 8635240

Showing the first eight; more decompositions exist.
