Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524070, here are decompositions:

23 + 31524047 = 31524070
47 + 31524023 = 31524070
59 + 31524011 = 31524070
131 + 31523939 = 31524070
269 + 31523801 = 31524070
317 + 31523753 = 31524070
401 + 31523669 = 31524070
419 + 31523651 = 31524070

Showing the first eight; more decompositions exist.
