Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947880, here are decompositions:

7 + 947873 = 947880
19 + 947861 = 947880
23 + 947857 = 947880
29 + 947851 = 947880
47 + 947833 = 947880
61 + 947819 = 947880
97 + 947783 = 947880
107 + 947773 = 947880

Showing the first eight; more decompositions exist.
