Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947922, here are decompositions:

5 + 947917 = 947922
11 + 947911 = 947922
29 + 947893 = 947922
61 + 947861 = 947922
71 + 947851 = 947922
89 + 947833 = 947922
103 + 947819 = 947922
139 + 947783 = 947922

Showing the first eight; more decompositions exist.
