Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457526, here are decompositions:

13 + 31457513 = 31457526
47 + 31457479 = 31457526
73 + 31457453 = 31457526
179 + 31457347 = 31457526
197 + 31457329 = 31457526
223 + 31457303 = 31457526
229 + 31457297 = 31457526
239 + 31457287 = 31457526

Showing the first eight; more decompositions exist.
