Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524914, here are decompositions:

151 + 31524763 = 31524914
193 + 31524721 = 31524914
241 + 31524673 = 31524914
271 + 31524643 = 31524914
307 + 31524607 = 31524914
373 + 31524541 = 31524914
397 + 31524517 = 31524914
571 + 31524343 = 31524914

Showing the first eight; more decompositions exist.
