Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978180, here are decompositions:

23 + 978157 = 978180
29 + 978151 = 978180
31 + 978149 = 978180
67 + 978113 = 978180
89 + 978091 = 978180
101 + 978079 = 978180
103 + 978077 = 978180
107 + 978073 = 978180

Showing the first eight; more decompositions exist.
