Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545262, here are decompositions:

5 + 545257 = 545262
23 + 545239 = 545262
31 + 545231 = 545262
59 + 545203 = 545262
73 + 545189 = 545262
101 + 545161 = 545262
131 + 545131 = 545262
173 + 545089 = 545262

Showing the first eight; more decompositions exist.
