Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978186, here are decompositions:

5 + 978181 = 978186
7 + 978179 = 978186
29 + 978157 = 978186
37 + 978149 = 978186
73 + 978113 = 978186
107 + 978079 = 978186
109 + 978077 = 978186
113 + 978073 = 978186

Showing the first eight; more decompositions exist.
