Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978164, here are decompositions:

7 + 978157 = 978164
13 + 978151 = 978164
73 + 978091 = 978164
97 + 978067 = 978164
127 + 978037 = 978164
157 + 978007 = 978164
163 + 978001 = 978164
193 + 977971 = 978164

Showing the first eight; more decompositions exist.
