Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622618, here are decompositions:

7 + 8622611 = 8622618
41 + 8622577 = 8622618
89 + 8622529 = 8622618
97 + 8622521 = 8622618
107 + 8622511 = 8622618
127 + 8622491 = 8622618
131 + 8622487 = 8622618
149 + 8622469 = 8622618

Showing the first eight; more decompositions exist.
