Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102104, here are decompositions:

3 + 102101 = 102104
43 + 102061 = 102104
61 + 102043 = 102104
73 + 102031 = 102104
103 + 102001 = 102104
127 + 101977 = 102104
241 + 101863 = 102104
271 + 101833 = 102104

Showing the first eight; more decompositions exist.
