Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 543644, here are decompositions:

7 + 543637 = 543644
37 + 543607 = 543644
43 + 543601 = 543644
181 + 543463 = 543644
331 + 543313 = 543644
337 + 543307 = 543644
421 + 543223 = 543644
457 + 543187 = 543644

Showing the first eight; more decompositions exist.
