Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561172, here are decompositions:

3 + 33561169 = 33561172
11 + 33561161 = 33561172
83 + 33561089 = 33561172
149 + 33561023 = 33561172
173 + 33560999 = 33561172
233 + 33560939 = 33561172
431 + 33560741 = 33561172
443 + 33560729 = 33561172

Showing the first eight; more decompositions exist.
