Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185906, here are decompositions:

3 + 185903 = 185906
13 + 185893 = 185906
37 + 185869 = 185906
73 + 185833 = 185906
109 + 185797 = 185906
139 + 185767 = 185906
157 + 185749 = 185906
199 + 185707 = 185906

Showing the first eight; more decompositions exist.
