Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185826, here are decompositions:

5 + 185821 = 185826
7 + 185819 = 185826
13 + 185813 = 185826
29 + 185797 = 185826
37 + 185789 = 185826
59 + 185767 = 185826
73 + 185753 = 185826
79 + 185747 = 185826

Showing the first eight; more decompositions exist.
