Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634438, here are decompositions:

11 + 8634427 = 8634438
17 + 8634421 = 8634438
41 + 8634397 = 8634438
47 + 8634391 = 8634438
67 + 8634371 = 8634438
79 + 8634359 = 8634438
139 + 8634299 = 8634438
179 + 8634259 = 8634438

Showing the first eight; more decompositions exist.
