Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474066, here are decompositions:

5 + 31474061 = 31474066
23 + 31474043 = 31474066
59 + 31474007 = 31474066
89 + 31473977 = 31474066
149 + 31473917 = 31474066
179 + 31473887 = 31474066
227 + 31473839 = 31474066
257 + 31473809 = 31474066

Showing the first eight; more decompositions exist.
