Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33530442, here are decompositions:

41 + 33530401 = 33530442
73 + 33530369 = 33530442
83 + 33530359 = 33530442
89 + 33530353 = 33530442
139 + 33530303 = 33530442
163 + 33530279 = 33530442
181 + 33530261 = 33530442
193 + 33530249 = 33530442

Showing the first eight; more decompositions exist.
