Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622450, here are decompositions:

29 + 8622421 = 8622450
37 + 8622413 = 8622450
59 + 8622391 = 8622450
71 + 8622379 = 8622450
97 + 8622353 = 8622450
107 + 8622343 = 8622450
113 + 8622337 = 8622450
127 + 8622323 = 8622450

Showing the first eight; more decompositions exist.
