Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572442, here are decompositions:

61 + 33572381 = 33572442
89 + 33572353 = 33572442
103 + 33572339 = 33572442
109 + 33572333 = 33572442
131 + 33572311 = 33572442
139 + 33572303 = 33572442
191 + 33572251 = 33572442
223 + 33572219 = 33572442

Showing the first eight; more decompositions exist.
