Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474174, here are decompositions:

3 + 31474171 = 31474174
101 + 31474073 = 31474174
113 + 31474061 = 31474174
131 + 31474043 = 31474174
167 + 31474007 = 31474174
197 + 31473977 = 31474174
257 + 31473917 = 31474174
311 + 31473863 = 31474174

Showing the first eight; more decompositions exist.
