Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978490, here are decompositions:

11 + 978479 = 978490
17 + 978473 = 978490
41 + 978449 = 978490
101 + 978389 = 978490
131 + 978359 = 978490
167 + 978323 = 978490
251 + 978239 = 978490
257 + 978233 = 978490

Showing the first eight; more decompositions exist.
