Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 543642, here are decompositions:

5 + 543637 = 543642
31 + 543611 = 543642
41 + 543601 = 543642
89 + 543553 = 543642
103 + 543539 = 543642
139 + 543503 = 543642
179 + 543463 = 543642
263 + 543379 = 543642

Showing the first eight; more decompositions exist.
