Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947906, here are decompositions:

13 + 947893 = 947906
73 + 947833 = 947906
103 + 947803 = 947906
163 + 947743 = 947906
199 + 947707 = 947906
367 + 947539 = 947906
397 + 947509 = 947906
457 + 947449 = 947906

Showing the first eight; more decompositions exist.
