Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978564, here are decompositions:

23 + 978541 = 978564
43 + 978521 = 978564
53 + 978511 = 978564
73 + 978491 = 978564
101 + 978463 = 978564
107 + 978457 = 978564
137 + 978427 = 978564
151 + 978413 = 978564

Showing the first eight; more decompositions exist.
