Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947946, here are decompositions:

19 + 947927 = 947946
29 + 947917 = 947946
53 + 947893 = 947946
73 + 947873 = 947946
89 + 947857 = 947946
113 + 947833 = 947946
127 + 947819 = 947946
163 + 947783 = 947946

Showing the first eight; more decompositions exist.
