Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638492, here are decompositions:

11 + 8638481 = 8638492
29 + 8638463 = 8638492
41 + 8638451 = 8638492
89 + 8638403 = 8638492
113 + 8638379 = 8638492
173 + 8638319 = 8638492
251 + 8638241 = 8638492
263 + 8638229 = 8638492

Showing the first eight; more decompositions exist.
