Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528442, here are decompositions:

173 + 33528269 = 33528442
293 + 33528149 = 33528442
401 + 33528041 = 33528442
419 + 33528023 = 33528442
443 + 33527999 = 33528442
449 + 33527993 = 33528442
461 + 33527981 = 33528442
599 + 33527843 = 33528442

Showing the first eight; more decompositions exist.
