Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173940, here are decompositions:

7 + 173933 = 173940
17 + 173923 = 173940
23 + 173917 = 173940
31 + 173909 = 173940
43 + 173897 = 173940
73 + 173867 = 173940
79 + 173861 = 173940
89 + 173851 = 173940

Showing the first eight; more decompositions exist.
