Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102904, here are decompositions:

23 + 102881 = 102904
107 + 102797 = 102904
227 + 102677 = 102904
251 + 102653 = 102904
257 + 102647 = 102904
293 + 102611 = 102904
311 + 102593 = 102904
317 + 102587 = 102904

Showing the first eight; more decompositions exist.
