Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33517920, here are decompositions:

13 + 33517907 = 33517920
17 + 33517903 = 33517920
19 + 33517901 = 33517920
41 + 33517879 = 33517920
47 + 33517873 = 33517920
71 + 33517849 = 33517920
109 + 33517811 = 33517920
127 + 33517793 = 33517920

Showing the first eight; more decompositions exist.
