Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727164, here are decompositions:

3 + 8727161 = 8727164
7 + 8727157 = 8727164
73 + 8727091 = 8727164
97 + 8727067 = 8727164
181 + 8726983 = 8727164
211 + 8726953 = 8727164
241 + 8726923 = 8727164
487 + 8726677 = 8727164

Showing the first eight; more decompositions exist.
