Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622474, here are decompositions:

5 + 8622469 = 8622474
11 + 8622463 = 8622474
13 + 8622461 = 8622474
53 + 8622421 = 8622474
61 + 8622413 = 8622474
83 + 8622391 = 8622474
101 + 8622373 = 8622474
131 + 8622343 = 8622474

Showing the first eight; more decompositions exist.
