Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33530172, here are decompositions:

101 + 33530071 = 33530172
113 + 33530059 = 33530172
149 + 33530023 = 33530172
163 + 33530009 = 33530172
251 + 33529921 = 33530172
271 + 33529901 = 33530172
311 + 33529861 = 33530172
349 + 33529823 = 33530172

Showing the first eight; more decompositions exist.
