Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463494, here are decompositions:

5 + 31463489 = 31463494
11 + 31463483 = 31463494
17 + 31463477 = 31463494
107 + 31463387 = 31463494
131 + 31463363 = 31463494
173 + 31463321 = 31463494
233 + 31463261 = 31463494
281 + 31463213 = 31463494

Showing the first eight; more decompositions exist.
