Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33530278, here are decompositions:

11 + 33530267 = 33530278
17 + 33530261 = 33530278
29 + 33530249 = 33530278
269 + 33530009 = 33530278
491 + 33529787 = 33530278
521 + 33529757 = 33530278
557 + 33529721 = 33530278
839 + 33529439 = 33530278

Showing the first eight; more decompositions exist.
