Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947966, here are decompositions:

3 + 947963 = 947966
7 + 947959 = 947966
73 + 947893 = 947966
109 + 947857 = 947966
163 + 947803 = 947966
193 + 947773 = 947966
223 + 947743 = 947966
307 + 947659 = 947966

Showing the first eight; more decompositions exist.
