Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33544820, here are decompositions:

37 + 33544783 = 33544820
103 + 33544717 = 33544820
109 + 33544711 = 33544820
151 + 33544669 = 33544820
181 + 33544639 = 33544820
223 + 33544597 = 33544820
241 + 33544579 = 33544820
307 + 33544513 = 33544820

Showing the first eight; more decompositions exist.
