Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640300, here are decompositions:

13 + 8640287 = 8640300
37 + 8640263 = 8640300
41 + 8640259 = 8640300
59 + 8640241 = 8640300
79 + 8640221 = 8640300
89 + 8640211 = 8640300
103 + 8640197 = 8640300
113 + 8640187 = 8640300

Showing the first eight; more decompositions exist.
