Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646312, here are decompositions:

13 + 8646299 = 8646312
19 + 8646293 = 8646312
43 + 8646269 = 8646312
53 + 8646259 = 8646312
79 + 8646233 = 8646312
89 + 8646223 = 8646312
131 + 8646181 = 8646312
149 + 8646163 = 8646312

Showing the first eight; more decompositions exist.
