Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185946, here are decompositions:

23 + 185923 = 185946
29 + 185917 = 185946
43 + 185903 = 185946
53 + 185893 = 185946
73 + 185873 = 185946
97 + 185849 = 185946
113 + 185833 = 185946
127 + 185819 = 185946

Showing the first eight; more decompositions exist.
