Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640264, here are decompositions:

5 + 8640259 = 8640264
13 + 8640251 = 8640264
23 + 8640241 = 8640264
43 + 8640221 = 8640264
53 + 8640211 = 8640264
67 + 8640197 = 8640264
103 + 8640161 = 8640264
131 + 8640133 = 8640264

Showing the first eight; more decompositions exist.
