Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504198, here are decompositions:

71 + 31504127 = 31504198
101 + 31504097 = 31504198
227 + 31503971 = 31504198
269 + 31503929 = 31504198
281 + 31503917 = 31504198
311 + 31503887 = 31504198
389 + 31503809 = 31504198
419 + 31503779 = 31504198

Showing the first eight; more decompositions exist.
