Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978570, here are decompositions:

29 + 978541 = 978570
59 + 978511 = 978570
79 + 978491 = 978570
97 + 978473 = 978570
107 + 978463 = 978570
113 + 978457 = 978570
157 + 978413 = 978570
167 + 978403 = 978570

Showing the first eight; more decompositions exist.
