Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456854, here are decompositions:

5 + 31456849 = 31456854
67 + 31456787 = 31456854
73 + 31456781 = 31456854
113 + 31456741 = 31456854
127 + 31456727 = 31456854
151 + 31456703 = 31456854
257 + 31456597 = 31456854
307 + 31456547 = 31456854

Showing the first eight; more decompositions exist.
