Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17884, here are decompositions:

3 + 17881 = 17884
47 + 17837 = 17884
101 + 17783 = 17884
137 + 17747 = 17884
227 + 17657 = 17884
257 + 17627 = 17884
311 + 17573 = 17884
401 + 17483 = 17884

Showing the first eight; more decompositions exist.
