Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40164, here are decompositions:

11 + 40153 = 40164
13 + 40151 = 40164
37 + 40127 = 40164
41 + 40123 = 40164
53 + 40111 = 40164
71 + 40093 = 40164
101 + 40063 = 40164
127 + 40037 = 40164

Showing the first eight; more decompositions exist.
