Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28948, here are decompositions:

47 + 28901 = 28948
89 + 28859 = 28948
131 + 28817 = 28948
197 + 28751 = 28948
251 + 28697 = 28948
317 + 28631 = 28948
389 + 28559 = 28948
401 + 28547 = 28948

Showing the first eight; more decompositions exist.
