Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10490, here are decompositions:

3 + 10487 = 10490
13 + 10477 = 10490
31 + 10459 = 10490
37 + 10453 = 10490
61 + 10429 = 10490
157 + 10333 = 10490
223 + 10267 = 10490
313 + 10177 = 10490

Showing the first eight; more decompositions exist.
