Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011978, here are decompositions:

5 + 1011973 = 1011978
17 + 1011961 = 1011978
31 + 1011947 = 1011978
41 + 1011937 = 1011978
61 + 1011917 = 1011978
89 + 1011889 = 1011978
151 + 1011827 = 1011978
179 + 1011799 = 1011978

Showing the first eight; more decompositions exist.
