Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33500172, here are decompositions:

19 + 33500153 = 33500172
61 + 33500111 = 33500172
71 + 33500101 = 33500172
89 + 33500083 = 33500172
163 + 33500009 = 33500172
229 + 33499943 = 33500172
263 + 33499909 = 33500172
269 + 33499903 = 33500172

Showing the first eight; more decompositions exist.
