Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640318, here are decompositions:

31 + 8640287 = 8640318
59 + 8640259 = 8640318
67 + 8640251 = 8640318
97 + 8640221 = 8640318
107 + 8640211 = 8640318
131 + 8640187 = 8640318
149 + 8640169 = 8640318
157 + 8640161 = 8640318

Showing the first eight; more decompositions exist.
