Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33530380, here are decompositions:

11 + 33530369 = 33530380
53 + 33530327 = 33530380
71 + 33530309 = 33530380
101 + 33530279 = 33530380
113 + 33530267 = 33530380
131 + 33530249 = 33530380
197 + 33530183 = 33530380
479 + 33529901 = 33530380

Showing the first eight; more decompositions exist.
