Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621158, here are decompositions:

5 + 8621153 = 8621158
11 + 8621147 = 8621158
71 + 8621087 = 8621158
107 + 8621051 = 8621158
149 + 8621009 = 8621158
311 + 8620847 = 8621158
317 + 8620841 = 8621158
401 + 8620757 = 8621158

Showing the first eight; more decompositions exist.
