Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185940, here are decompositions:

17 + 185923 = 185940
23 + 185917 = 185940
37 + 185903 = 185940
43 + 185897 = 185940
47 + 185893 = 185940
67 + 185873 = 185940
71 + 185869 = 185940
107 + 185833 = 185940

Showing the first eight; more decompositions exist.
