Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978406, here are decompositions:

3 + 978403 = 978406
17 + 978389 = 978406
47 + 978359 = 978406
59 + 978347 = 978406
83 + 978323 = 978406
137 + 978269 = 978406
167 + 978239 = 978406
173 + 978233 = 978406

Showing the first eight; more decompositions exist.
