Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545906, here are decompositions:

7 + 545899 = 545906
13 + 545893 = 545906
43 + 545863 = 545906
79 + 545827 = 545906
157 + 545749 = 545906
307 + 545599 = 545906
373 + 545533 = 545906
379 + 545527 = 545906

Showing the first eight; more decompositions exist.
