Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10000, here are decompositions:

59 + 9941 = 10000
71 + 9929 = 10000
113 + 9887 = 10000
149 + 9851 = 10000
167 + 9833 = 10000
197 + 9803 = 10000
233 + 9767 = 10000
251 + 9749 = 10000

Showing the first eight; more decompositions exist.
