Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105164, here are decompositions:

67 + 105097 = 105164
127 + 105037 = 105164
193 + 104971 = 105164
211 + 104953 = 105164
313 + 104851 = 105164
337 + 104827 = 105164
421 + 104743 = 105164
457 + 104707 = 105164

Showing the first eight; more decompositions exist.
