Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 543042, here are decompositions:

13 + 543029 = 543042
23 + 543019 = 543042
43 + 542999 = 543042
61 + 542981 = 543042
103 + 542939 = 543042
109 + 542933 = 543042
131 + 542911 = 543042
151 + 542891 = 543042

Showing the first eight; more decompositions exist.
