Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622612, here are decompositions:

83 + 8622529 = 8622612
101 + 8622511 = 8622612
113 + 8622499 = 8622612
139 + 8622473 = 8622612
149 + 8622463 = 8622612
151 + 8622461 = 8622612
191 + 8622421 = 8622612
199 + 8622413 = 8622612

Showing the first eight; more decompositions exist.
