Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622148, here are decompositions:

11 + 8622137 = 8622148
107 + 8622041 = 8622148
131 + 8622017 = 8622148
137 + 8622011 = 8622148
251 + 8621897 = 8622148
281 + 8621867 = 8622148
317 + 8621831 = 8622148
401 + 8621747 = 8622148

Showing the first eight; more decompositions exist.
