Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33547072, here are decompositions:

29 + 33547043 = 33547072
59 + 33547013 = 33547072
131 + 33546941 = 33547072
179 + 33546893 = 33547072
233 + 33546839 = 33547072
359 + 33546713 = 33547072
389 + 33546683 = 33547072
401 + 33546671 = 33547072

Showing the first eight; more decompositions exist.
