Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10290, here are decompositions:

17 + 10273 = 10290
19 + 10271 = 10290
23 + 10267 = 10290
31 + 10259 = 10290
37 + 10253 = 10290
43 + 10247 = 10290
47 + 10243 = 10290
67 + 10223 = 10290

Showing the first eight; more decompositions exist.
