Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77942, here are decompositions:

13 + 77929 = 77942
43 + 77899 = 77942
79 + 77863 = 77942
103 + 77839 = 77942
181 + 77761 = 77942
199 + 77743 = 77942
211 + 77731 = 77942
223 + 77719 = 77942

Showing the first eight; more decompositions exist.
