Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33625420, here are decompositions:

53 + 33625367 = 33625420
89 + 33625331 = 33625420
107 + 33625313 = 33625420
149 + 33625271 = 33625420
167 + 33625253 = 33625420
281 + 33625139 = 33625420
359 + 33625061 = 33625420
401 + 33625019 = 33625420

Showing the first eight; more decompositions exist.
