Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635228, here are decompositions:

29 + 8635199 = 8635228
167 + 8635061 = 8635228
179 + 8635049 = 8635228
257 + 8634971 = 8635228
281 + 8634947 = 8635228
311 + 8634917 = 8635228
347 + 8634881 = 8635228
389 + 8634839 = 8635228

Showing the first eight; more decompositions exist.
