Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457676, here are decompositions:

73 + 31457603 = 31457676
163 + 31457513 = 31457676
197 + 31457479 = 31457676
223 + 31457453 = 31457676
227 + 31457449 = 31457676
293 + 31457383 = 31457676
347 + 31457329 = 31457676
373 + 31457303 = 31457676

Showing the first eight; more decompositions exist.
