Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524588, here are decompositions:

19 + 31524569 = 31524588
47 + 31524541 = 31524588
71 + 31524517 = 31524588
79 + 31524509 = 31524588
89 + 31524499 = 31524588
257 + 31524331 = 31524588
311 + 31524277 = 31524588
317 + 31524271 = 31524588

Showing the first eight; more decompositions exist.
