Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523824, here are decompositions:

23 + 31523801 = 31523824
71 + 31523753 = 31523824
173 + 31523651 = 31523824
191 + 31523633 = 31523824
347 + 31523477 = 31523824
383 + 31523441 = 31523824
443 + 31523381 = 31523824
557 + 31523267 = 31523824

Showing the first eight; more decompositions exist.
