Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457366, here are decompositions:

19 + 31457347 = 31457366
37 + 31457329 = 31457366
79 + 31457287 = 31457366
97 + 31457269 = 31457366
139 + 31457227 = 31457366
163 + 31457203 = 31457366
439 + 31456927 = 31457366
463 + 31456903 = 31457366

Showing the first eight; more decompositions exist.
