Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545402, here are decompositions:

31 + 545371 = 545402
73 + 545329 = 545402
163 + 545239 = 545402
199 + 545203 = 545402
241 + 545161 = 545402
271 + 545131 = 545402
313 + 545089 = 545402
373 + 545029 = 545402

Showing the first eight; more decompositions exist.
