Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185902, here are decompositions:

5 + 185897 = 185902
29 + 185873 = 185902
53 + 185849 = 185902
71 + 185831 = 185902
83 + 185819 = 185902
89 + 185813 = 185902
113 + 185789 = 185902
149 + 185753 = 185902

Showing the first eight; more decompositions exist.
