Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 949920, here are decompositions:

17 + 949903 = 949920
29 + 949891 = 949920
31 + 949889 = 949920
67 + 949853 = 949920
71 + 949849 = 949920
109 + 949811 = 949920
131 + 949789 = 949920
149 + 949771 = 949920

Showing the first eight; more decompositions exist.
