Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640368, here are decompositions:

19 + 8640349 = 8640368
31 + 8640337 = 8640368
109 + 8640259 = 8640368
127 + 8640241 = 8640368
157 + 8640211 = 8640368
181 + 8640187 = 8640368
199 + 8640169 = 8640368
367 + 8640001 = 8640368

Showing the first eight; more decompositions exist.
