Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947942, here are decompositions:

31 + 947911 = 947942
109 + 947833 = 947942
139 + 947803 = 947942
199 + 947743 = 947942
223 + 947719 = 947942
283 + 947659 = 947942
433 + 947509 = 947942
601 + 947341 = 947942

Showing the first eight; more decompositions exist.
