Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33471540, here are decompositions:

7 + 33471533 = 33471540
29 + 33471511 = 33471540
43 + 33471497 = 33471540
61 + 33471479 = 33471540
71 + 33471469 = 33471540
101 + 33471439 = 33471540
103 + 33471437 = 33471540
107 + 33471433 = 33471540

Showing the first eight; more decompositions exist.
