Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185898, here are decompositions:

5 + 185893 = 185898
29 + 185869 = 185898
67 + 185831 = 185898
79 + 185819 = 185898
101 + 185797 = 185898
109 + 185789 = 185898
131 + 185767 = 185898
149 + 185749 = 185898

Showing the first eight; more decompositions exist.
