Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646240, here are decompositions:

7 + 8646233 = 8646240
13 + 8646227 = 8646240
17 + 8646223 = 8646240
19 + 8646221 = 8646240
59 + 8646181 = 8646240
137 + 8646103 = 8646240
179 + 8646061 = 8646240
181 + 8646059 = 8646240

Showing the first eight; more decompositions exist.
