Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947844, here are decompositions:

11 + 947833 = 947844
41 + 947803 = 947844
61 + 947783 = 947844
71 + 947773 = 947844
97 + 947747 = 947844
101 + 947743 = 947844
103 + 947741 = 947844
137 + 947707 = 947844

Showing the first eight; more decompositions exist.
