Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19876, here are decompositions:

23 + 19853 = 19876
83 + 19793 = 19876
113 + 19763 = 19876
137 + 19739 = 19876
149 + 19727 = 19876
167 + 19709 = 19876
179 + 19697 = 19876
293 + 19583 = 19876

Showing the first eight; more decompositions exist.
