Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647464, here are decompositions:

5 + 8647459 = 8647464
17 + 8647447 = 8647464
47 + 8647417 = 8647464
53 + 8647411 = 8647464
71 + 8647393 = 8647464
73 + 8647391 = 8647464
97 + 8647367 = 8647464
191 + 8647273 = 8647464

Showing the first eight; more decompositions exist.
