Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524074, here are decompositions:

31 + 31524043 = 31524074
61 + 31524013 = 31524074
157 + 31523917 = 31524074
193 + 31523881 = 31524074
223 + 31523851 = 31524074
271 + 31523803 = 31524074
313 + 31523761 = 31524074
367 + 31523707 = 31524074

Showing the first eight; more decompositions exist.
