Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978688, here are decompositions:

5 + 978683 = 978688
41 + 978647 = 978688
71 + 978617 = 978688
89 + 978599 = 978688
167 + 978521 = 978688
197 + 978491 = 978688
239 + 978449 = 978688
401 + 978287 = 978688

Showing the first eight; more decompositions exist.
