Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474198, here are decompositions:

137 + 31474061 = 31474198
191 + 31474007 = 31474198
227 + 31473971 = 31474198
281 + 31473917 = 31474198
311 + 31473887 = 31474198
359 + 31473839 = 31474198
389 + 31473809 = 31474198
419 + 31473779 = 31474198

Showing the first eight; more decompositions exist.
