Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 975978, here are decompositions:

11 + 975967 = 975978
37 + 975941 = 975978
71 + 975907 = 975978
79 + 975899 = 975978
109 + 975869 = 975978
131 + 975847 = 975978
151 + 975827 = 975978
167 + 975811 = 975978

Showing the first eight; more decompositions exist.
