Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997164, here are decompositions:

11 + 997153 = 997164
13 + 997151 = 997164
17 + 997147 = 997164
23 + 997141 = 997164
41 + 997123 = 997164
43 + 997121 = 997164
53 + 997111 = 997164
61 + 997103 = 997164

Showing the first eight; more decompositions exist.
