Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978358, here are decompositions:

11 + 978347 = 978358
71 + 978287 = 978358
89 + 978269 = 978358
149 + 978209 = 978358
179 + 978179 = 978358
281 + 978077 = 978358
317 + 978041 = 978358
347 + 978011 = 978358

Showing the first eight; more decompositions exist.
