Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474006, here are decompositions:

29 + 31473977 = 31474006
89 + 31473917 = 31474006
167 + 31473839 = 31474006
197 + 31473809 = 31474006
227 + 31473779 = 31474006
569 + 31473437 = 31474006
593 + 31473413 = 31474006
647 + 31473359 = 31474006

Showing the first eight; more decompositions exist.
