Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947930, here are decompositions:

3 + 947927 = 947930
13 + 947917 = 947930
19 + 947911 = 947930
37 + 947893 = 947930
73 + 947857 = 947930
79 + 947851 = 947930
97 + 947833 = 947930
127 + 947803 = 947930

Showing the first eight; more decompositions exist.
