Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978258, here are decompositions:

19 + 978239 = 978258
41 + 978217 = 978258
79 + 978179 = 978258
101 + 978157 = 978258
107 + 978151 = 978258
109 + 978149 = 978258
167 + 978091 = 978258
179 + 978079 = 978258

Showing the first eight; more decompositions exist.
