Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525160, here are decompositions:

23 + 33525137 = 33525160
83 + 33525077 = 33525160
101 + 33525059 = 33525160
197 + 33524963 = 33525160
233 + 33524927 = 33525160
269 + 33524891 = 33525160
359 + 33524801 = 33525160
419 + 33524741 = 33525160

Showing the first eight; more decompositions exist.
