Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637474, here are decompositions:

7 + 8637467 = 8637474
23 + 8637451 = 8637474
47 + 8637427 = 8637474
101 + 8637373 = 8637474
137 + 8637337 = 8637474
151 + 8637323 = 8637474
163 + 8637311 = 8637474
173 + 8637301 = 8637474

Showing the first eight; more decompositions exist.
