Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474036, here are decompositions:

3 + 31474033 = 31474036
29 + 31474007 = 31474036
59 + 31473977 = 31474036
149 + 31473887 = 31474036
173 + 31473863 = 31474036
197 + 31473839 = 31474036
227 + 31473809 = 31474036
257 + 31473779 = 31474036

Showing the first eight; more decompositions exist.
