Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185838, here are decompositions:

5 + 185833 = 185838
7 + 185831 = 185838
17 + 185821 = 185838
19 + 185819 = 185838
41 + 185797 = 185838
71 + 185767 = 185838
89 + 185749 = 185838
101 + 185737 = 185838

Showing the first eight; more decompositions exist.
