Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556820, here are decompositions:

97 + 33556723 = 33556820
109 + 33556711 = 33556820
139 + 33556681 = 33556820
223 + 33556597 = 33556820
313 + 33556507 = 33556820
337 + 33556483 = 33556820
397 + 33556423 = 33556820
421 + 33556399 = 33556820

Showing the first eight; more decompositions exist.
