Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545358, here are decompositions:

29 + 545329 = 545358
67 + 545291 = 545358
101 + 545257 = 545358
127 + 545231 = 545358
197 + 545161 = 545358
227 + 545131 = 545358
241 + 545117 = 545358
269 + 545089 = 545358

Showing the first eight; more decompositions exist.
