Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978418, here are decompositions:

5 + 978413 = 978418
29 + 978389 = 978418
59 + 978359 = 978418
71 + 978347 = 978418
131 + 978287 = 978418
149 + 978269 = 978418
179 + 978239 = 978418
239 + 978179 = 978418

Showing the first eight; more decompositions exist.
