Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546628, here are decompositions:

7 + 31546621 = 31546628
31 + 31546597 = 31546628
37 + 31546591 = 31546628
241 + 31546387 = 31546628
277 + 31546351 = 31546628
349 + 31546279 = 31546628
397 + 31546231 = 31546628
499 + 31546129 = 31546628

Showing the first eight; more decompositions exist.
