Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622678, here are decompositions:

67 + 8622611 = 8622678
101 + 8622577 = 8622678
149 + 8622529 = 8622678
157 + 8622521 = 8622678
167 + 8622511 = 8622678
179 + 8622499 = 8622678
191 + 8622487 = 8622678
257 + 8622421 = 8622678

Showing the first eight; more decompositions exist.
