Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457396, here are decompositions:

13 + 31457383 = 31457396
67 + 31457329 = 31457396
109 + 31457287 = 31457396
127 + 31457269 = 31457396
193 + 31457203 = 31457396
277 + 31457119 = 31457396
547 + 31456849 = 31457396
577 + 31456819 = 31457396

Showing the first eight; more decompositions exist.
