Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33529072, here are decompositions:

29 + 33529043 = 33529072
41 + 33529031 = 33529072
131 + 33528941 = 33529072
233 + 33528839 = 33529072
251 + 33528821 = 33529072
383 + 33528689 = 33529072
419 + 33528653 = 33529072
443 + 33528629 = 33529072

Showing the first eight; more decompositions exist.
