Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640348, here are decompositions:

11 + 8640337 = 8640348
19 + 8640329 = 8640348
61 + 8640287 = 8640348
89 + 8640259 = 8640348
97 + 8640251 = 8640348
107 + 8640241 = 8640348
127 + 8640221 = 8640348
137 + 8640211 = 8640348

Showing the first eight; more decompositions exist.
