Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640464, here are decompositions:

13 + 8640451 = 8640464
37 + 8640427 = 8640464
73 + 8640391 = 8640464
127 + 8640337 = 8640464
223 + 8640241 = 8640464
277 + 8640187 = 8640464
331 + 8640133 = 8640464
463 + 8640001 = 8640464

Showing the first eight; more decompositions exist.
