Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978906, here are decompositions:

23 + 978883 = 978906
43 + 978863 = 978906
53 + 978853 = 978906
67 + 978839 = 978906
107 + 978799 = 978906
109 + 978797 = 978906
157 + 978749 = 978906
163 + 978743 = 978906

Showing the first eight; more decompositions exist.
