Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27942, here are decompositions:

23 + 27919 = 27942
41 + 27901 = 27942
59 + 27883 = 27942
139 + 27803 = 27942
149 + 27793 = 27942
151 + 27791 = 27942
163 + 27779 = 27942
179 + 27763 = 27942

Showing the first eight; more decompositions exist.
