Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978194, here are decompositions:

13 + 978181 = 978194
37 + 978157 = 978194
43 + 978151 = 978194
103 + 978091 = 978194
127 + 978067 = 978194
157 + 978037 = 978194
163 + 978031 = 978194
193 + 978001 = 978194

Showing the first eight; more decompositions exist.
