Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474008, here are decompositions:

17 + 31473991 = 31474008
31 + 31473977 = 31474008
37 + 31473971 = 31474008
101 + 31473907 = 31474008
107 + 31473901 = 31474008
197 + 31473811 = 31474008
199 + 31473809 = 31474008
227 + 31473781 = 31474008

Showing the first eight; more decompositions exist.
