Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947982, here are decompositions:

19 + 947963 = 947982
23 + 947959 = 947982
71 + 947911 = 947982
89 + 947893 = 947982
109 + 947873 = 947982
131 + 947851 = 947982
149 + 947833 = 947982
163 + 947819 = 947982

Showing the first eight; more decompositions exist.
