Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545528, here are decompositions:

7 + 545521 = 545528
31 + 545497 = 545528
79 + 545449 = 545528
157 + 545371 = 545528
199 + 545329 = 545528
271 + 545257 = 545528
367 + 545161 = 545528
397 + 545131 = 545528

Showing the first eight; more decompositions exist.
