Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89940, here are decompositions:

17 + 89923 = 89940
23 + 89917 = 89940
31 + 89909 = 89940
41 + 89899 = 89940
43 + 89897 = 89940
73 + 89867 = 89940
101 + 89839 = 89940
107 + 89833 = 89940

Showing the first eight; more decompositions exist.
