Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638474, here are decompositions:

3 + 8638471 = 8638474
11 + 8638463 = 8638474
17 + 8638457 = 8638474
23 + 8638451 = 8638474
71 + 8638403 = 8638474
101 + 8638373 = 8638474
137 + 8638337 = 8638474
191 + 8638283 = 8638474

Showing the first eight; more decompositions exist.
