Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740164, here are decompositions:

7 + 8740157 = 8740164
47 + 8740117 = 8740164
53 + 8740111 = 8740164
67 + 8740097 = 8740164
127 + 8740037 = 8740164
197 + 8739967 = 8740164
211 + 8739953 = 8740164
227 + 8739937 = 8740164

Showing the first eight; more decompositions exist.
