Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185872, here are decompositions:

3 + 185869 = 185872
23 + 185849 = 185872
41 + 185831 = 185872
53 + 185819 = 185872
59 + 185813 = 185872
83 + 185789 = 185872
149 + 185723 = 185872
173 + 185699 = 185872

Showing the first eight; more decompositions exist.
