Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102304, here are decompositions:

3 + 102301 = 102304
5 + 102299 = 102304
11 + 102293 = 102304
53 + 102251 = 102304
71 + 102233 = 102304
101 + 102203 = 102304
107 + 102197 = 102304
113 + 102191 = 102304

Showing the first eight; more decompositions exist.
