Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572420, here are decompositions:

3 + 33572417 = 33572420
43 + 33572377 = 33572420
67 + 33572353 = 33572420
73 + 33572347 = 33572420
109 + 33572311 = 33572420
229 + 33572191 = 33572420
337 + 33572083 = 33572420
379 + 33572041 = 33572420

Showing the first eight; more decompositions exist.
