Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524980, here are decompositions:

13 + 31524967 = 31524980
43 + 31524937 = 31524980
307 + 31524673 = 31524980
337 + 31524643 = 31524980
373 + 31524607 = 31524980
439 + 31524541 = 31524980
457 + 31524523 = 31524980
463 + 31524517 = 31524980

Showing the first eight; more decompositions exist.
