Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89942, here are decompositions:

3 + 89939 = 89942
19 + 89923 = 89942
43 + 89899 = 89942
103 + 89839 = 89942
109 + 89833 = 89942
163 + 89779 = 89942
271 + 89671 = 89942
283 + 89659 = 89942

Showing the first eight; more decompositions exist.
