Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978328, here are decompositions:

5 + 978323 = 978328
41 + 978287 = 978328
59 + 978269 = 978328
89 + 978239 = 978328
149 + 978179 = 978328
179 + 978149 = 978328
251 + 978077 = 978328
257 + 978071 = 978328

Showing the first eight; more decompositions exist.
