Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622266, here are decompositions:

43 + 8622223 = 8622266
139 + 8622127 = 8622266
277 + 8621989 = 8622266
283 + 8621983 = 8622266
307 + 8621959 = 8622266
397 + 8621869 = 8622266
409 + 8621857 = 8622266
439 + 8621827 = 8622266

Showing the first eight; more decompositions exist.
