Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978204, here are decompositions:

23 + 978181 = 978204
47 + 978157 = 978204
53 + 978151 = 978204
113 + 978091 = 978204
127 + 978077 = 978204
131 + 978073 = 978204
137 + 978067 = 978204
151 + 978053 = 978204

Showing the first eight; more decompositions exist.
