Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646372, here are decompositions:

11 + 8646361 = 8646372
43 + 8646329 = 8646372
73 + 8646299 = 8646372
79 + 8646293 = 8646372
103 + 8646269 = 8646372
113 + 8646259 = 8646372
139 + 8646233 = 8646372
149 + 8646223 = 8646372

Showing the first eight; more decompositions exist.
