Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978162, here are decompositions:

5 + 978157 = 978162
11 + 978151 = 978162
13 + 978149 = 978162
71 + 978091 = 978162
83 + 978079 = 978162
89 + 978073 = 978162
109 + 978053 = 978162
113 + 978049 = 978162

Showing the first eight; more decompositions exist.
