Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33530540, here are decompositions:

3 + 33530537 = 33530540
139 + 33530401 = 33530540
181 + 33530359 = 33530540
193 + 33530347 = 33530540
619 + 33529921 = 33530540
751 + 33529789 = 33530540
829 + 33529711 = 33530540
937 + 33529603 = 33530540

Showing the first eight; more decompositions exist.
