Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545412, here are decompositions:

41 + 545371 = 545412
83 + 545329 = 545412
173 + 545239 = 545412
181 + 545231 = 545412
199 + 545213 = 545412
223 + 545189 = 545412
251 + 545161 = 545412
269 + 545143 = 545412

Showing the first eight; more decompositions exist.
