Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78942, here are decompositions:

13 + 78929 = 78942
23 + 78919 = 78942
41 + 78901 = 78942
53 + 78889 = 78942
89 + 78853 = 78942
103 + 78839 = 78942
139 + 78803 = 78942
151 + 78791 = 78942

Showing the first eight; more decompositions exist.
