Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457552, here are decompositions:

73 + 31457479 = 31457552
103 + 31457449 = 31457552
211 + 31457341 = 31457552
223 + 31457329 = 31457552
241 + 31457311 = 31457552
283 + 31457269 = 31457552
349 + 31457203 = 31457552
433 + 31457119 = 31457552

Showing the first eight; more decompositions exist.
