Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553720, here are decompositions:

23 + 33553697 = 33553720
41 + 33553679 = 33553720
59 + 33553661 = 33553720
71 + 33553649 = 33553720
107 + 33553613 = 33553720
113 + 33553607 = 33553720
173 + 33553547 = 33553720
257 + 33553463 = 33553720

Showing the first eight; more decompositions exist.
