Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101942, here are decompositions:

3 + 101939 = 101942
13 + 101929 = 101942
73 + 101869 = 101942
79 + 101863 = 101942
103 + 101839 = 101942
109 + 101833 = 101942
193 + 101749 = 101942
223 + 101719 = 101942

Showing the first eight; more decompositions exist.
