Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493530, here are decompositions:

17 + 33493513 = 33493530
47 + 33493483 = 33493530
139 + 33493391 = 33493530
157 + 33493373 = 33493530
167 + 33493363 = 33493530
223 + 33493307 = 33493530
251 + 33493279 = 33493530
277 + 33493253 = 33493530

Showing the first eight; more decompositions exist.
