Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102804, here are decompositions:

7 + 102797 = 102804
11 + 102793 = 102804
41 + 102763 = 102804
43 + 102761 = 102804
103 + 102701 = 102804
127 + 102677 = 102804
131 + 102673 = 102804
137 + 102667 = 102804

Showing the first eight; more decompositions exist.
