Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524974, here are decompositions:

7 + 31524967 = 31524974
37 + 31524937 = 31524974
181 + 31524793 = 31524974
211 + 31524763 = 31524974
331 + 31524643 = 31524974
367 + 31524607 = 31524974
433 + 31524541 = 31524974
457 + 31524517 = 31524974

Showing the first eight; more decompositions exist.
