Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978912, here are decompositions:

5 + 978907 = 978912
29 + 978883 = 978912
41 + 978871 = 978912
59 + 978853 = 978912
61 + 978851 = 978912
73 + 978839 = 978912
113 + 978799 = 978912
139 + 978773 = 978912

Showing the first eight; more decompositions exist.
