Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622100, here are decompositions:

29 + 8622071 = 8622100
59 + 8622041 = 8622100
83 + 8622017 = 8622100
89 + 8622011 = 8622100
167 + 8621933 = 8622100
173 + 8621927 = 8622100
233 + 8621867 = 8622100
239 + 8621861 = 8622100

Showing the first eight; more decompositions exist.
