Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640248, here are decompositions:

7 + 8640241 = 8640248
37 + 8640211 = 8640248
61 + 8640187 = 8640248
79 + 8640169 = 8640248
139 + 8640109 = 8640248
271 + 8639977 = 8640248
349 + 8639899 = 8640248
439 + 8639809 = 8640248

Showing the first eight; more decompositions exist.
