Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457276, here are decompositions:

7 + 31457269 = 31457276
73 + 31457203 = 31457276
127 + 31457149 = 31457276
157 + 31457119 = 31457276
349 + 31456927 = 31457276
373 + 31456903 = 31457276
457 + 31456819 = 31457276
607 + 31456669 = 31457276

Showing the first eight; more decompositions exist.
