Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524842, here are decompositions:

3 + 31524839 = 31524842
79 + 31524763 = 31524842
199 + 31524643 = 31524842
373 + 31524469 = 31524842
439 + 31524403 = 31524842
499 + 31524343 = 31524842
541 + 31524301 = 31524842
571 + 31524271 = 31524842

Showing the first eight; more decompositions exist.
