Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622488, here are decompositions:

19 + 8622469 = 8622488
67 + 8622421 = 8622488
97 + 8622391 = 8622488
109 + 8622379 = 8622488
151 + 8622337 = 8622488
157 + 8622331 = 8622488
181 + 8622307 = 8622488
487 + 8622001 = 8622488

Showing the first eight; more decompositions exist.
