Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 543142, here are decompositions:

3 + 543139 = 543142
11 + 543131 = 543142
29 + 543113 = 543142
113 + 543029 = 543142
191 + 542951 = 543142
251 + 542891 = 543142
269 + 542873 = 543142
311 + 542831 = 543142

Showing the first eight; more decompositions exist.
