Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978408, here are decompositions:

5 + 978403 = 978408
19 + 978389 = 978408
59 + 978349 = 978408
61 + 978347 = 978408
71 + 978337 = 978408
131 + 978277 = 978408
139 + 978269 = 978408
191 + 978217 = 978408

Showing the first eight; more decompositions exist.
