Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545428, here are decompositions:

41 + 545387 = 545428
137 + 545291 = 545428
197 + 545231 = 545428
239 + 545189 = 545428
311 + 545117 = 545428
449 + 544979 = 545428
467 + 544961 = 545428
491 + 544937 = 545428

Showing the first eight; more decompositions exist.
