Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546610, here are decompositions:

13 + 31546597 = 31546610
19 + 31546591 = 31546610
37 + 31546573 = 31546610
127 + 31546483 = 31546610
223 + 31546387 = 31546610
241 + 31546369 = 31546610
307 + 31546303 = 31546610
331 + 31546279 = 31546610

Showing the first eight; more decompositions exist.
