Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10286, here are decompositions:

13 + 10273 = 10286
19 + 10267 = 10286
43 + 10243 = 10286
109 + 10177 = 10286
127 + 10159 = 10286
193 + 10093 = 10286
277 + 10009 = 10286
313 + 9973 = 10286

Showing the first eight; more decompositions exist.
