Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33472940, here are decompositions:

3 + 33472937 = 33472940
37 + 33472903 = 33472940
157 + 33472783 = 33472940
181 + 33472759 = 33472940
271 + 33472669 = 33472940
337 + 33472603 = 33472940
547 + 33472393 = 33472940
577 + 33472363 = 33472940

Showing the first eight; more decompositions exist.
