Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572540, here are decompositions:

3 + 33572537 = 33572540
7 + 33572533 = 33572540
13 + 33572527 = 33572540
19 + 33572521 = 33572540
37 + 33572503 = 33572540
163 + 33572377 = 33572540
193 + 33572347 = 33572540
229 + 33572311 = 33572540

Showing the first eight; more decompositions exist.
