Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947816, here are decompositions:

13 + 947803 = 947816
43 + 947773 = 947816
73 + 947743 = 947816
97 + 947719 = 947816
109 + 947707 = 947816
157 + 947659 = 947816
277 + 947539 = 947816
307 + 947509 = 947816

Showing the first eight; more decompositions exist.
