Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742164, here are decompositions:

3 + 8742161 = 8742164
7 + 8742157 = 8742164
31 + 8742133 = 8742164
43 + 8742121 = 8742164
61 + 8742103 = 8742164
97 + 8742067 = 8742164
127 + 8742037 = 8742164
181 + 8741983 = 8742164

Showing the first eight; more decompositions exist.
