Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545304, here are decompositions:

13 + 545291 = 545304
37 + 545267 = 545304
47 + 545257 = 545304
73 + 545231 = 545304
101 + 545203 = 545304
163 + 545141 = 545304
173 + 545131 = 545304
211 + 545093 = 545304

Showing the first eight; more decompositions exist.
