Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945978, here are decompositions:

17 + 945961 = 945978
29 + 945949 = 945978
37 + 945941 = 945978
41 + 945937 = 945978
71 + 945907 = 945978
79 + 945899 = 945978
97 + 945881 = 945978
127 + 945851 = 945978

Showing the first eight; more decompositions exist.
