Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640234, here are decompositions:

13 + 8640221 = 8640234
23 + 8640211 = 8640234
37 + 8640197 = 8640234
47 + 8640187 = 8640234
73 + 8640161 = 8640234
101 + 8640133 = 8640234
233 + 8640001 = 8640234
257 + 8639977 = 8640234

Showing the first eight; more decompositions exist.
