Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622156, here are decompositions:

19 + 8622137 = 8622156
29 + 8622127 = 8622156
43 + 8622113 = 8622156
139 + 8622017 = 8622156
149 + 8622007 = 8622156
167 + 8621989 = 8622156
173 + 8621983 = 8622156
197 + 8621959 = 8622156

Showing the first eight; more decompositions exist.
