Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572490, here are decompositions:

43 + 33572447 = 33572490
73 + 33572417 = 33572490
109 + 33572381 = 33572490
113 + 33572377 = 33572490
137 + 33572353 = 33572490
139 + 33572351 = 33572490
151 + 33572339 = 33572490
157 + 33572333 = 33572490

Showing the first eight; more decompositions exist.
