Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33530140, here are decompositions:

131 + 33530009 = 33530140
233 + 33529907 = 33530140
239 + 33529901 = 33530140
269 + 33529871 = 33530140
317 + 33529823 = 33530140
353 + 33529787 = 33530140
383 + 33529757 = 33530140
401 + 33529739 = 33530140

Showing the first eight; more decompositions exist.
