Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102942, here are decompositions:

11 + 102931 = 102942
13 + 102929 = 102942
29 + 102913 = 102942
31 + 102911 = 102942
61 + 102881 = 102942
71 + 102871 = 102942
83 + 102859 = 102942
101 + 102841 = 102942

Showing the first eight; more decompositions exist.
