Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978198, here are decompositions:

17 + 978181 = 978198
19 + 978179 = 978198
41 + 978157 = 978198
47 + 978151 = 978198
107 + 978091 = 978198
127 + 978071 = 978198
131 + 978067 = 978198
149 + 978049 = 978198

Showing the first eight; more decompositions exist.
