Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640414, here are decompositions:

5 + 8640409 = 8640414
7 + 8640407 = 8640414
23 + 8640391 = 8640414
127 + 8640287 = 8640414
151 + 8640263 = 8640414
163 + 8640251 = 8640414
173 + 8640241 = 8640414
193 + 8640221 = 8640414

Showing the first eight; more decompositions exist.
