Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 543542, here are decompositions:

3 + 543539 = 543542
79 + 543463 = 543542
163 + 543379 = 543542
193 + 543349 = 543542
229 + 543313 = 543542
283 + 543259 = 543542
379 + 543163 = 543542
523 + 543019 = 543542

Showing the first eight; more decompositions exist.
