Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521140, here are decompositions:

41 + 33521099 = 33521140
53 + 33521087 = 33521140
83 + 33521057 = 33521140
101 + 33521039 = 33521140
131 + 33521009 = 33521140
137 + 33521003 = 33521140
167 + 33520973 = 33521140
173 + 33520967 = 33521140

Showing the first eight; more decompositions exist.
