Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452526, here are decompositions:

5 + 31452521 = 31452526
29 + 31452497 = 31452526
107 + 31452419 = 31452526
293 + 31452233 = 31452526
317 + 31452209 = 31452526
353 + 31452173 = 31452526
389 + 31452137 = 31452526
557 + 31451969 = 31452526

Showing the first eight; more decompositions exist.
