Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524674, here are decompositions:

31 + 31524643 = 31524674
67 + 31524607 = 31524674
151 + 31524523 = 31524674
157 + 31524517 = 31524674
271 + 31524403 = 31524674
331 + 31524343 = 31524674
373 + 31524301 = 31524674
397 + 31524277 = 31524674

Showing the first eight; more decompositions exist.
