Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978498, here are decompositions:

7 + 978491 = 978498
19 + 978479 = 978498
41 + 978457 = 978498
71 + 978427 = 978498
109 + 978389 = 978498
139 + 978359 = 978498
149 + 978349 = 978498
151 + 978347 = 978498

Showing the first eight; more decompositions exist.
