Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555820, here are decompositions:

3 + 33555817 = 33555820
83 + 33555737 = 33555820
173 + 33555647 = 33555820
191 + 33555629 = 33555820
257 + 33555563 = 33555820
293 + 33555527 = 33555820
359 + 33555461 = 33555820
401 + 33555419 = 33555820

Showing the first eight; more decompositions exist.
