Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463676, here are decompositions:

89 + 31463587 = 31463676
149 + 31463527 = 31463676
157 + 31463519 = 31463676
193 + 31463483 = 31463676
199 + 31463477 = 31463676
269 + 31463407 = 31463676
313 + 31463363 = 31463676
347 + 31463329 = 31463676

Showing the first eight; more decompositions exist.
