Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978856, here are decompositions:

3 + 978853 = 978856
5 + 978851 = 978856
17 + 978839 = 978856
59 + 978797 = 978856
83 + 978773 = 978856
107 + 978749 = 978856
113 + 978743 = 978856
167 + 978689 = 978856

Showing the first eight; more decompositions exist.
