Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 543666, here are decompositions:

5 + 543661 = 543666
7 + 543659 = 543666
29 + 543637 = 543666
59 + 543607 = 543666
73 + 543593 = 543666
113 + 543553 = 543666
127 + 543539 = 543666
157 + 543509 = 543666

Showing the first eight; more decompositions exist.
