Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640192, here are decompositions:

5 + 8640187 = 8640192
23 + 8640169 = 8640192
31 + 8640161 = 8640192
59 + 8640133 = 8640192
83 + 8640109 = 8640192
179 + 8640013 = 8640192
191 + 8640001 = 8640192
241 + 8639951 = 8640192

Showing the first eight; more decompositions exist.
