Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978254, here are decompositions:

31 + 978223 = 978254
37 + 978217 = 978254
73 + 978181 = 978254
97 + 978157 = 978254
103 + 978151 = 978254
163 + 978091 = 978254
181 + 978073 = 978254
223 + 978031 = 978254

Showing the first eight; more decompositions exist.
