Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545198, here are decompositions:

37 + 545161 = 545198
67 + 545131 = 545198
109 + 545089 = 545198
271 + 544927 = 545198
337 + 544861 = 545198
439 + 544759 = 545198
499 + 544699 = 545198
547 + 544651 = 545198

Showing the first eight; more decompositions exist.
