Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456892, here are decompositions:

43 + 31456849 = 31456892
73 + 31456819 = 31456892
151 + 31456741 = 31456892
223 + 31456669 = 31456892
241 + 31456651 = 31456892
463 + 31456429 = 31456892
601 + 31456291 = 31456892
613 + 31456279 = 31456892

Showing the first eight; more decompositions exist.
