Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524564, here are decompositions:

23 + 31524541 = 31524564
31 + 31524533 = 31524564
41 + 31524523 = 31524564
47 + 31524517 = 31524564
233 + 31524331 = 31524564
263 + 31524301 = 31524564
271 + 31524293 = 31524564
293 + 31524271 = 31524564

Showing the first eight; more decompositions exist.
