Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512942, here are decompositions:

13 + 512929 = 512942
43 + 512899 = 512942
139 + 512803 = 512942
163 + 512779 = 512942
181 + 512761 = 512942
229 + 512713 = 512942
271 + 512671 = 512942
349 + 512593 = 512942

Showing the first eight; more decompositions exist.
