Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509172, here are decompositions:

23 + 33509149 = 33509172
29 + 33509143 = 33509172
43 + 33509129 = 33509172
101 + 33509071 = 33509172
131 + 33509041 = 33509172
199 + 33508973 = 33509172
269 + 33508903 = 33509172
271 + 33508901 = 33509172

Showing the first eight; more decompositions exist.
