Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978910, here are decompositions:

3 + 978907 = 978910
47 + 978863 = 978910
59 + 978851 = 978910
71 + 978839 = 978910
89 + 978821 = 978910
113 + 978797 = 978910
137 + 978773 = 978910
167 + 978743 = 978910

Showing the first eight; more decompositions exist.
