Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640354, here are decompositions:

5 + 8640349 = 8640354
17 + 8640337 = 8640354
67 + 8640287 = 8640354
103 + 8640251 = 8640354
113 + 8640241 = 8640354
157 + 8640197 = 8640354
167 + 8640187 = 8640354
193 + 8640161 = 8640354

Showing the first eight; more decompositions exist.
