Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557072, here are decompositions:

61 + 33557011 = 33557072
79 + 33556993 = 33557072
103 + 33556969 = 33557072
151 + 33556921 = 33557072
193 + 33556879 = 33557072
349 + 33556723 = 33557072
541 + 33556531 = 33557072
613 + 33556459 = 33557072

Showing the first eight; more decompositions exist.
