Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621088, here are decompositions:

5 + 8621083 = 8621088
11 + 8621077 = 8621088
37 + 8621051 = 8621088
41 + 8621047 = 8621088
71 + 8621017 = 8621088
79 + 8621009 = 8621088
137 + 8620951 = 8621088
139 + 8620949 = 8621088

Showing the first eight; more decompositions exist.
