Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457336, here are decompositions:

7 + 31457329 = 31457336
67 + 31457269 = 31457336
109 + 31457227 = 31457336
409 + 31456927 = 31457336
433 + 31456903 = 31457336
487 + 31456849 = 31457336
739 + 31456597 = 31457336
907 + 31456429 = 31457336

Showing the first eight; more decompositions exist.
