Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545384, here are decompositions:

13 + 545371 = 545384
127 + 545257 = 545384
181 + 545203 = 545384
223 + 545161 = 545384
241 + 545143 = 545384
421 + 544963 = 545384
457 + 544927 = 545384
487 + 544897 = 545384

Showing the first eight; more decompositions exist.
