Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640360, here are decompositions:

11 + 8640349 = 8640360
23 + 8640337 = 8640360
31 + 8640329 = 8640360
73 + 8640287 = 8640360
97 + 8640263 = 8640360
101 + 8640259 = 8640360
109 + 8640251 = 8640360
139 + 8640221 = 8640360

Showing the first eight; more decompositions exist.
