Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65900, here are decompositions:

19 + 65881 = 65900
61 + 65839 = 65900
73 + 65827 = 65900
139 + 65761 = 65900
181 + 65719 = 65900
193 + 65707 = 65900
199 + 65701 = 65900
223 + 65677 = 65900

Showing the first eight; more decompositions exist.
