Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33625220, here are decompositions:

3 + 33625217 = 33625220
43 + 33625177 = 33625220
61 + 33625159 = 33625220
193 + 33625027 = 33625220
229 + 33624991 = 33625220
337 + 33624883 = 33625220
457 + 33624763 = 33625220
487 + 33624733 = 33625220

Showing the first eight; more decompositions exist.
