Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978508, here are decompositions:

17 + 978491 = 978508
29 + 978479 = 978508
59 + 978449 = 978508
149 + 978359 = 978508
239 + 978269 = 978508
269 + 978239 = 978508
359 + 978149 = 978508
431 + 978077 = 978508

Showing the first eight; more decompositions exist.
