Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638192, here are decompositions:

5 + 8638187 = 8638192
41 + 8638151 = 8638192
53 + 8638139 = 8638192
71 + 8638121 = 8638192
131 + 8638061 = 8638192
149 + 8638043 = 8638192
239 + 8637953 = 8638192
263 + 8637929 = 8638192

Showing the first eight; more decompositions exist.
