Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622660, here are decompositions:

83 + 8622577 = 8622660
97 + 8622563 = 8622660
131 + 8622529 = 8622660
139 + 8622521 = 8622660
149 + 8622511 = 8622660
173 + 8622487 = 8622660
191 + 8622469 = 8622660
197 + 8622463 = 8622660

Showing the first eight; more decompositions exist.
