Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474206, here are decompositions:

149 + 31474057 = 31474206
163 + 31474043 = 31474206
173 + 31474033 = 31474206
199 + 31474007 = 31474206
229 + 31473977 = 31474206
359 + 31473847 = 31474206
367 + 31473839 = 31474206
397 + 31473809 = 31474206

Showing the first eight; more decompositions exist.
