Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476284, here are decompositions:

97 + 31476187 = 31476284
127 + 31476157 = 31476284
211 + 31476073 = 31476284
271 + 31476013 = 31476284
331 + 31475953 = 31476284
373 + 31475911 = 31476284
457 + 31475827 = 31476284
487 + 31475797 = 31476284

Showing the first eight; more decompositions exist.
