Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101804, here are decompositions:

7 + 101797 = 101804
67 + 101737 = 101804
103 + 101701 = 101804
151 + 101653 = 101804
163 + 101641 = 101804
193 + 101611 = 101804
223 + 101581 = 101804
271 + 101533 = 101804

Showing the first eight; more decompositions exist.
