Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33612072, here are decompositions:

19 + 33612053 = 33612072
31 + 33612041 = 33612072
73 + 33611999 = 33612072
113 + 33611959 = 33612072
251 + 33611821 = 33612072
281 + 33611791 = 33612072
349 + 33611723 = 33612072
359 + 33611713 = 33612072

Showing the first eight; more decompositions exist.
