Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978546, here are decompositions:

5 + 978541 = 978546
67 + 978479 = 978546
73 + 978473 = 978546
83 + 978463 = 978546
89 + 978457 = 978546
97 + 978449 = 978546
157 + 978389 = 978546
197 + 978349 = 978546

Showing the first eight; more decompositions exist.
