Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528482, here are decompositions:

23 + 31528459 = 31528482
31 + 31528451 = 31528482
109 + 31528373 = 31528482
191 + 31528291 = 31528482
199 + 31528283 = 31528482
241 + 31528241 = 31528482
269 + 31528213 = 31528482
311 + 31528171 = 31528482

Showing the first eight; more decompositions exist.
