Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531040, here are decompositions:

29 + 33531011 = 33531040
41 + 33530999 = 33531040
71 + 33530969 = 33531040
227 + 33530813 = 33531040
251 + 33530789 = 33531040
281 + 33530759 = 33531040
311 + 33530729 = 33531040
443 + 33530597 = 33531040

Showing the first eight; more decompositions exist.
