Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978538, here are decompositions:

17 + 978521 = 978538
47 + 978491 = 978538
59 + 978479 = 978538
89 + 978449 = 978538
149 + 978389 = 978538
179 + 978359 = 978538
191 + 978347 = 978538
251 + 978287 = 978538

Showing the first eight; more decompositions exist.
