Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731164, here are decompositions:

11 + 8731153 = 8731164
23 + 8731141 = 8731164
53 + 8731111 = 8731164
61 + 8731103 = 8731164
67 + 8731097 = 8731164
137 + 8731027 = 8731164
181 + 8730983 = 8731164
251 + 8730913 = 8731164

Showing the first eight; more decompositions exist.
