Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28954, here are decompositions:

5 + 28949 = 28954
53 + 28901 = 28954
83 + 28871 = 28954
137 + 28817 = 28954
251 + 28703 = 28954
257 + 28697 = 28954
293 + 28661 = 28954
311 + 28643 = 28954

Showing the first eight; more decompositions exist.
