Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165804, here are decompositions:

5 + 165799 = 165804
83 + 165721 = 165804
97 + 165707 = 165804
101 + 165703 = 165804
103 + 165701 = 165804
131 + 165673 = 165804
137 + 165667 = 165804
151 + 165653 = 165804

Showing the first eight; more decompositions exist.
