Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971904, here are decompositions:

5 + 971899 = 971904
41 + 971863 = 971904
47 + 971857 = 971904
53 + 971851 = 971904
71 + 971833 = 971904
83 + 971821 = 971904
137 + 971767 = 971904
151 + 971753 = 971904

Showing the first eight; more decompositions exist.
