Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622398, here are decompositions:

7 + 8622391 = 8622398
19 + 8622379 = 8622398
61 + 8622337 = 8622398
67 + 8622331 = 8622398
97 + 8622301 = 8622398
157 + 8622241 = 8622398
271 + 8622127 = 8622398
397 + 8622001 = 8622398

Showing the first eight; more decompositions exist.
