Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622648, here are decompositions:

37 + 8622611 = 8622648
71 + 8622577 = 8622648
127 + 8622521 = 8622648
137 + 8622511 = 8622648
149 + 8622499 = 8622648
157 + 8622491 = 8622648
179 + 8622469 = 8622648
227 + 8622421 = 8622648

Showing the first eight; more decompositions exist.
