Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185904, here are decompositions:

7 + 185897 = 185904
11 + 185893 = 185904
31 + 185873 = 185904
71 + 185833 = 185904
73 + 185831 = 185904
83 + 185821 = 185904
107 + 185797 = 185904
137 + 185767 = 185904

Showing the first eight; more decompositions exist.
