Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545972, here are decompositions:

13 + 545959 = 545972
43 + 545929 = 545972
61 + 545911 = 545972
73 + 545899 = 545972
79 + 545893 = 545972
109 + 545863 = 545972
181 + 545791 = 545972
199 + 545773 = 545972

Showing the first eight; more decompositions exist.
