Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622444, here are decompositions:

23 + 8622421 = 8622444
31 + 8622413 = 8622444
53 + 8622391 = 8622444
71 + 8622373 = 8622444
101 + 8622343 = 8622444
107 + 8622337 = 8622444
113 + 8622331 = 8622444
137 + 8622307 = 8622444

Showing the first eight; more decompositions exist.
