Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474026, here are decompositions:

19 + 31474007 = 31474026
109 + 31473917 = 31474026
139 + 31473887 = 31474026
163 + 31473863 = 31474026
179 + 31473847 = 31474026
293 + 31473733 = 31474026
433 + 31473593 = 31474026
443 + 31473583 = 31474026

Showing the first eight; more decompositions exist.
